The history of a pregnancy event followed by a D&C leading to secondary amenorrhea or hypomenorrhea is typical. Hysteroscopy is the gold standard for diagnosis. Imaging by sonohysterography or hysterosalpingography will reveal the extent of the scar formation. Ultrasound is not a reliable method of diagnosing Asherman's Syndrome. Hormone studies show normal levels consistent with reproductive function.

A 2013 review concluded that there were no studies reporting on the link between intrauterine adhesions and long-term reproductive outcome after miscarriage, while similar pregnancy outcomes were reported subsequent to surgical management (e.g. D&C), medical management or conservative management (that is, watchful waiting). There is an association between surgical intervention in the uterus and the development of intrauterine adhesions, and between intrauterine adhesions and pregnancy outcomes, but there is still no clear evidence of any method of prevention of adverse pregnancy outcomes.

In theory, the recently pregnant uterus is particularly soft under the influence of hormones and hence, easily injured. D&C (including dilation and curettage, dilation and evacuation/suction curettage and manual vacuum aspiration) is a blind, invasive procedure, making it difficult to avoid endometrial trauma. Medical alternatives to D&C for evacuation of retained placenta/products of conception exist including misoprostol and mifepristone. Studies show this less invasive and cheaper method to be an efficacious, safe and an acceptable alternative to surgical management for most women. It was suggested as early as in 1993 that the incidence of IUA might be lower following medical evacuation (e.g. Misoprostol) of the uterus, thus avoiding any intrauterine instrumentation. So far, one study supports this proposal, showing that women who were treated for missed miscarriage with misoprostol did not develop IUA, while 7.7% of those undergoing D&C did. The advantage of misoprostol is that it can be used for evacuation not only following miscarriage, but also following birth for retained placenta or hemorrhaging.

Alternatively, D&C could be performed under ultrasound guidance rather than as a blind procedure. This would enable the surgeon to end scraping the lining when all retained tissue has been removed, avoiding injury.

Early monitoring during pregnancy to identify miscarriage can prevent the development of, or as the case may be, the recurrence of AS, as the longer the period after fetal death following D&C, the more likely adhesions may be to occur. Therefore, immediate evacuation following fetal death may prevent IUA.

The use of hysteroscopic surgery instead of D&C to remove retained products of conception or placenta is another alternative that could theoretically improve future pregnancy outcomes, although it could be less effective if tissue is abundant. Also, hysteroscopy is not a widely or routinely used technique and requires expertise.

There is no data to indicate that suction D&C is less likely than sharp curette to result in Asherman's. A recent article describes three cases of women who developed intrauterine adhesions following manual vacuum aspiration.

Adenomyosis can vary widely in the extent and location of its invasion within the uterus. As a result, there are no established pathognomonic features to allow for a definitive diagnosis of adenomyosis through non-invasive imaging. Nevertheless, non-invasive imaging techniques such as transvaginal ultrasonography (TVUS) and magnetic resonance imaging (MRI) can both be used to strongly suggest the diagnosis of adenomyosis, guide treatment options, and monitor response to treatment. Indeed, TVUS and MRI are the only two practical means available to establish a pre-surgical diagnosis.

Magnetic resonance imaging (MRI) provides slightly better diagnostic capability compared to TVUS, due to the increased ability of MRI to differentiate objectively between different types of soft tissue. This is possible with MRI's higher spatial and contrast resolution. Overall, it is estimated that MRI has a sensitivity of 74% and specificity of 91% for the detection of adenomyosis. Diagnosis through MRI focuses predominately upon investigating the junctional zone. The uterus will have a thickened junctional zone with darker/diminished signal on both T1 and T2 weighted sequences.

Three objective measures of the junctional zone can be used to diagnose adenomyosis.

1. A thickness of the junctional zone greater than 8–12 mm. Less than 8 mm is normal.

2. A junctional zone width being greater than 40% of the width of the myometrium.

3. Variability in the width of the junctional zone being greater than 5 mm.

Interspersed within the thickened, darker signal of the junctional zone, one will often see foci of hyperintensity (bright spots) on the T2 weighted scans representing small cystically dilatated glands or more acute sites of microhemorrhage.

MRI is limited by other factors, but not by calcified uterine fibroids (as is ultrasound). In particular, MRI is better able to differentiate adenomyosis from multiple small uterine fibroids.

A transvaginal ultrasound can reveal the condition.

Helpful techniques to investigate the uterine structure are transvaginal ultrasonography and sonohysterography, hysterosalpingography, MRI, and hysteroscopy. More recently 3-D ultrasonography has been advocated as an excellent non-invasive method to delineate the condition.

The major differential diagnosis is the uterine septum. The lack of agreement to separate these two entities makes it difficult to assess the results in the literature.

Early diagnosis is important and today facilitated by the use of sonography and the quantitative human chorionic gonadotropin (hCG) assay. As in other cases of ectopic pregnancy, risk factors are: previous tubal pregnancy, IVF therapy, tubal surgery, and a history of sexual infection.

Typical symptoms of an interstitial pregnancy are the classic signs of ectopic pregnancy, namely abdominal pain and vaginal bleeding. Hemorrhagic shock is found in almost a quarter of patients.; this explains the relatively high mortality rate.

In pregnant patients, sonography is the primary method to make the diagnosis, even when patients have no symptoms. The paucity of myometrium around the gestational sac is diagnostic, while, in contrast, the angular pregnancy has at least 5 mm of myometrium on all of its sides. Ultrasonic criteria for the diagnosis include an empty uterine cavity, a gestational sac separate from the uterine cavity, and a myometrial thinning of less than 5 mm around the gestational sac; typically the "interstitial line sign"—an echogenic line from the endometrial cavity to the corner next to the gestational mass—is seen. MRI can be used particularly when it is important to distinguish between an interstitial and angular pregnancy.

On average, the gestational age at presentation is about 7–8 weeks. In a 2007 series, 22% of patients presented with rupture and hemorrhagic shock, while a third of the patients were asymptomatic; the remainder had abdominal pain and/or vaginal bleeding. Cases that are not diagnosed until surgery show an asymmetrical bulge in the upper corner of the uterus.

The exact incidence of maternal mortality related to placenta accreta and its complications is unknown, but has been reported to be as high as 6-7% in case series and surveys.

Patients with an ectopic pregnancy are generally at higher risk for a recurrence, however, there are no specific data for patients with an interstitial pregnancy. When a new pregnancy is diagnosed it is important to monitor the pregnancy by transvaginal sonography to assure that is it properly located, and that the surgically repaired area remains intact. Cesarean delivery is recommended to avoid uterine rupture during labor.

Pyometra describes an accumulation of pus in the uterine cavity. In order for pyometra to develop, there must be both an infection "and" blockage of cervix. Signs and symptoms include lower abdominal pain (suprapubic), rigors, fever, and the discharge of pus on introduction of a sound into the uterus.

Pyometra is treated with antibiotics, according to culture and sensitivity.

The uterus should be evacuated and contractions should be stimulated using intravenous oxytocin; hysterectomy (the removal of the uterus) may be needed in some cases.

About 1 out of 1000 lesions are or become malignant, typically as a leiomyosarcoma on histology. A sign that a lesion may be malignant is growth after menopause. There is no consensus among pathologists regarding the transformation of leiomyoma into a sarcoma.

The presence of a uterine fibroid versus an adnexal tumor is made. Fibroids can be mistaken for ovarian neoplasms. An uncommon tumor which may be mistaken for a fibroid is Sarcoma botryoides. It is more common in children and adolescents. Like a fibroid, it can also protrude from the vagina and is distinguished from fibroids. While palpation used in a pelvic examination can typically identify the presence of larger fibroids, gynecologic ultrasonography (ultrasound) has evolved as the standard tool to evaluate the uterus for fibroids. Sonography will depict the fibroids as focal masses with a heterogeneous texture, which usually cause shadowing of the ultrasound beam. The location can be determined and dimensions of the lesion measured. Also, magnetic resonance imaging (MRI) can be used to define the depiction of the size and location of the fibroids within the uterus.

Imaging modalities cannot clearly distinguish between the benign uterine leiomyoma and the malignant uterine leiomyosarcoma, however, the latter is quite rare. Fast growth or unexpected growth, such as enlargement of a lesion after menopause, raise the level of suspicion that the lesion might be a sarcoma. Also, with advanced malignant lesions, there may be evidence of local invasion. A biopsy is rarely performed and if performed, is rarely diagnostic. Should there be an uncertain diagnosis after ultrasounds and MRI imaging, surgery is generally indicated.

Other imaging techniques that may be helpful specifically in the evaluation of lesions that affect the uterine cavity are hysterosalpingography or sonohysterography.

Treatment may be delivery by caesarean section and abdominal hysterectomy if placenta accreta is diagnosed before birth. Oxytocin and antibiotics are used for post-surgical management. When there is partially separated placenta with focal accreta, best option is removal of placenta. If it is important to save the woman's uterus (for future pregnancies) then resection around the placenta may be successful. Conservative treatment can also be uterus sparing but may not be as successful and has a higher risk of complications.

Techniques include:

- Leaving the placenta in the uterus and curettage of uterus. Methotrexate has been used in this case.

- Intrauterine balloon catheterisation to compress blood vessels

- Embolisation of pelvic vessels

- Internal iliac artery ligation

- Bilateral uterine artery ligation

In cases where there is invasion of placental tissue and blood vessels into the bladder, it is treated in similar manner to abdominal pregnancy and manual placental removal is avoided. However, this may eventually need hysterectomy and/or partial cystectomy.

If the patient decides to proceed with a vaginal delivery, blood products for transfusion and an anesthesiologist are kept ready at delivery.

Most women with GTD can become pregnant again and can have children again. The risk of a further molar pregnancy is low. More than 98% of women who become pregnant following a molar pregnancy will not have a further hydatidiform mole or be at increased risk of complications.

In the past, it was seen as important not to get pregnant straight away after a GTD. Specialists recommended a waiting period of 6 months after the hCG levels become normal. Recently, this standpoint has been questioned. New medical data suggest that a significantly shorter waiting period after the hCG levels become normal is reasonable for approximately 97% of the patients with hydatidiform mole.

Multiple imaging modalities may be necessary to evaluate abnormalities of the nipple-areolar complex.

In two studies performed in Japan, high-resolution MRI with a microscopy coil yielding 0.137-mm in-plane resolution has been used to confirm the presence of abscesses, isolated fistulas and inflammation and to reveal their position in order to guide surgery.

Acute Endometritis is characterized by infection. The organisms most often isolated are believed to be because of compromised abortions, delivery, medical instrumentation, and retention of placental fragments. There is not enough evidence for the use of prophylactic antibiotics to prevent endometritis after manual removal of placental in vaginal birth. Histologically, neutrophilic infiltration of the endometrial tissue is present during acute endometritis. The clinical presentation is typically high fever and purulent vaginal discharge. Menstruation after acute endometritis is excessive and in uncomplicated cases can resolve after 2 weeks of clindamycin and gentamicin IV antibiotic treatment.

In certain populations, it has been associated with "Mycoplasma genitalium" and pelvic inflammatory disease.

Women with a hydatidiform mole have an excellent prognosis. Women with a malignant form of GTD usually have a very good prognosis.

Choriocarcinoma, for example, is an uncommon, yet almost always curable cancer. Although choriocarcinoma is a highly malignant tumour and a life-threatening disease, it is very sensitive to chemotherapy. Virtually all women with non-metastatic disease are cured and retain their fertility; the prognosis is also very good for those with metastatic (spreading) cancer, in the early stages, but fertility may be lost. Hysterectomy (surgical removal of the uterus) can also be offered to patients > 40 years of age or those for whom sterilisation is not an obstacle. Only a few women with GTD have a poor prognosis, e.g. some forms of stage IV GTN. The FIGO staging system is used. The risk can be estimated by scoring systems such as the "Modified WHO Prognostic Scoring System", wherein scores between 1 and 4 from various parameters are summed together:

In this scoring system, women with a score of 7 or greater are considered at high risk.

It is very important for malignant forms of GTD to be discovered in time. In Western countries, women with molar pregnancies are followed carefully; for instance, in the UK, all women who have had a molar pregnancy are registered at the National Trophoblastic Screening Centre. There are efforts in this direction in the developing countries too, and there have been improvements in these countries in the early detection of choriocarcinoma, thereby significantly reducing the mortality rate also in developing countries.

The occurrence of couvelaire uterus can be prevented by prevention of abruptio placentae. This include proper management of hypertensive states of pregnancy; treatment of maternal diseases like diabetes mellitus, and other collagen disease complicating pregnancy; prevention of trauma during pregnancy; mothers should also avoid smoking or consumption of alcohol during pregnancy.

No treatment required. It is standard practice for men with infertility and category IV prostatitis to be given a trial of antibiotics and/or anti-inflammatories, although evidence of efficacy are weak. Since signs of asymptomatic prostatic inflammation may sometimes be associated with prostate cancer, this can be addressed by tests that assess the ratio of free-to-total PSA. The results of these tests were significantly different in prostate cancer and category IV prostatitis in one study.

Diagnosis is through tests of semen, expressed prostatic secretion (EPS) or prostate tissue that reveal inflammation in the absence of symptoms.

Treatment is problematic unless an underlying endocrine disorder can be successfully diagnosed and treated.

A study by Goepel and Panhke provided indications that the inflammation should be controlled by bromocriptine even in absence of hyperprolactinemia.

Antibiotic treatment is given in case of acute inflammation. However, this alone is rarely effective, and the treatment of a subareaolar abscess is primarily surgical. In case of an acute abscess, incision and drainage are performed, followed by antibiotics treatment. However, in contrast to peripheral breast abscess which often resolves after antibiotics and incision and drainage, subareaolar breast abscess has a tendency to recur, often accompanied by the formation of fistulas leading from inflammation area to the skin surface. In many cases, in particular in patients with recurrent subareolar abscess, the excision of the affected lactiferous ducts is indicated, together with the excision of any chronic abscess or fistula. This can be performed using radial or circumareolar incision.

There is no universal agreement on what should be the standard way of treating the condition. In a recent review article, antibiotics treatment, ultrasound evaluation and, if fluid is present, ultrasound-guided fine needle aspiration of the abscess with an 18 gauge needle, under saline lavage until clear, has been suggested as initial line of treatment for breast abscess in puerperal and non-puerperal cases including central (subareolar) abscess (see breast abscess for details). Elsewhere, it has been stated that treatment of subareolar abscess is unlikely to work if it does not address the ducts as such.

Duct resection has been traditionally used to treat the condition; the original Hadfield procedure has been improved many times but long term success rate remains poor even for radical surgery. Petersen even suggests that damage caused by previous surgery is a frequent cause of subareolar abscesses. Goepel and Pahnke and other authors recommend performing surgeries only with concomitant bromocriptine treatment.

Comedo mastitis is a very rare form similar to granulomatous mastitis but with tissue necrosis. Because it is so rare it may be sometimes confused with comedo carcinoma of the breast although the conditions appear to be completely unrelated.

Parametritis is an inflammation of the parametrium (connective tissue adjacent to the uterus).

It is considered a form of pelvic inflammatory disease.

Parametritis is inflammation of the ligaments around the uterus. Parametritis is different from perimetritis which is inflammation of the serosa surrounding the uterus.

Oophoritis is an inflammation of the ovaries.

It is often seen in combination with salpingitis (inflammation of the fallopian tubes). It may develop in response to infection.
