MRI will help with the diagnosis of structural abnormality of the brain. Genetic testing may also be pursued.

In utero exposure to cocaine and other street drugs can lead to septo-optic dysplasia.

Prognoses for 3C syndrome vary widely based on the specific constellation of symptoms seen in an individual. Typically, the gravity of the prognosis correlates with the severity of the cardiac abnormalities. For children with less severe cardiac abnormalities, the developmental prognosis depends on the cerebellar abnormalities that are present. Severe cerebellar hypoplasia is associated with growth and speech delays, as well as hypotonia and general growth deficiencies.

The outcome of this disease is dependent on the severity of the cardiac defects. Approximately 1 in 3 children with this diagnosis require shunting for the hydrocephaly that is often a consequence. Some children require extra assistance or therapy for delayed psychomotor and speech development, including hypotonia.

The prognosis for vaginal atresia is one that is complicated. There are variations in patients' anatomic findings as well as an absence in consistent surgical techniques which makes it difficult to give a prognosis for this condition. Along with other conditions that give rise to an abnormal perineum (i.e. ambiguous genitalia and other various abnormalities that range from cloaca to urogenital sinus), individuals with vaginal atresia often report reconstruction as an outcome of treatment. Due to this, it is difficult to compare outcomes between individuals with vaginal atresia.

Fertility options for girls and women with Rokitansky-Mayer-Küster-Hauser syndrome has a bit more information. Girls and women who are born without a complete vagina, but still have a regular sized uterus more than likely will be able to become pregnant and have a baby. However, if the female is born with a tiny uterus, or without a uterus, they will not be able to have a baby. As the ovaries may be normal in this case, the egg may be fertilized with a donor's or partner's sperm. In this case, surrogacy, would be an option where there will be a gestational carrier to carry the pregnancy for the couple. Adoption may also be an option for females with Rokitansky-Mayer-Küster-Hauser syndrome. Another possibility could be uterine transplants, however this a new and developing form of treatment. Fertility options are being researched daily, so there can always be a new method available.

Any pain associated with Rokitansky-Mayer-Küster-Hauser syndrome comes from menstruation related cramping and can be treated with several ways. Individuals with this syndrome may be born with a uterine remnant (tiny uterus), which can fill with become filled with blood in the pelvic cavity causing pain. A medical professional can assess the severity of having a uterine remnant within each patient to determine if removal of the uterus is necessary.

Diagnosis is based on physical examination including radiographs of the hands and feet and imaging studies of the kidneys, bladder, and female reproductive tract. HOXA13 is the only gene known to be associated with HFGS. Approximately 60% of mutations are polyalanine expansions. Molecular genetic testing is clinically available.

Additional findings that may be present in HFGS according to the latest research are:

- Limited metacarpophalangeal flexion of the thumb or limited ability to oppose the thumb and fifth finger

- Hypoplastic thenar eminences

- Medial deviation of the great toe (hallux varus), a useful diagnostic sign when present

- Small great toenail

- Fifth-finger clinodactyly, secondary to a shortened middle phalanx

- Short feet

- Altered dermatoglyphics of the hands; when present, primarily involving distal placement of the axial triradius, lack of thenar or hypothenar patterning, low arches on the thumbs, thin ulnar loops (deficiency of radial loops and whorls), and a greatly reduced ridge count on the fingers

Radiographic findings

- Hypoplasia of the distal phalanx and first metacarpal of the thumbs and great toes

- Pointed distal phalanges of the thumb

- Lack of normal tufting of the distal phalanges of the great toes

- Fusions of the cuneiform to other tarsal bones or trapezium-scaphoid fusion of the carpals

- Short calcaneus

- Occasional bony fusions of the middle and distal phalanges of the second, third, fourth, or fifth toes

- Delayed carpal or tarsal maturation

- Metacarpophalangeal profile reflecting shortening of the first metacarpal, the first and second phalanges, and the second phalanx of the second and fifth digits

Urogenital Defects

Females may have the following:

- Vesicoureteral reflux secondary to ureteric incompetence

- Ectopic ureteral orifices

- Trigonal hypoplasia

- Hypospadiac urethra

- Subsymphyseal epispadias

- Patulous urethra

- Urinary incontinence (related to structural anomalies and weakness of the bladder sphincter muscle)

- Small hymenal opening

- Various degrees of incomplete Müllerian fusion with or without two cervices or a longitudinal vaginal septum

Males may have the following:

- Retrograde ejaculation (related to structural anomalies and weakness of the bladder sphincter muscle)

Doctors detect midline shift using a variety of methods. The most prominent measurement is done by a computed tomography (CT) scan and the CT Gold Standard is the standardized operating procedure for detecting MLS. Since the midline shift is often easily visible with a CT scan, the high precision of Magnetic Resonance Imaging (MRI) is not necessary, but can be used with equally adequate results. Newer methods such as bedside sonography can be used with neurocritical patients who cannot undergo some scans due to their dependence on ventilators or other care apparatuses. Sonography has proven satisfactory in the measurement of MLS, but is not expected to replace CT or MRI. Automated measurement algorithms are used for exact recognition and precision in measurements from an initial CT scan. A major benefit to using the automated recognition tools includes being able to measure even the most deformed brains because the method doesn’t depend on normal brain symmetry. Also, it lessens the chance of human error by detecting MLS from an entire image set compared to selecting the single most important slice, which allows the computer to do the work that was once manually done.

Other forms of uterine malformation need to be considered in the work-up for uterine septum. An arcuate uterus contains a residual cranial septum that is smaller than an incomplete septum but definitions between the two conditions are not standardized, - a cause for discrepancies in the literature.

A bicornuate uterus is sometimes confused with a septate uterus as in each situation the cavity is partitioned, however, in the former case the uterine body is cranially doubled (two uterine horns) while in the latter a single uterine body is present. The former represents a malformation of incomplete fusion of the Müllerian systems, and the latter of incomplete absorption. A hysterosalpingogram may not be able to distinguish between the two conditions. The differentiation, however, is important as a septum can be corrected by hysteroscopy, while a bicornuate uterus would be corrected by a metroplasty via laparotomy if necessary.

A pelvic examination may reveal a double vagina or double cervix that should be further investigated and may lead to the discovery of a uterine septum. In most patients, however, the pelvic examination is normal. Investigations are usually prompted on the basis of reproductive problems.

Helpful techniques to investigate a septum are transvaginal ultrasonography and sonohysterography, MRI, and hysteroscopy. More recently 3-D ultrasonography has been advocated as an excellent non-invasive method to delineate the condition. Prior to modern imaging hysterosalpingography was used to help diagnose the uterine septum, however, a bicornuate uterus may deliver a similar image.

An important category of septate uterus is the hybrid type a variant that may be misdiagnosed as bicornuate uterus when seen by laparoscopy Professor El Saman From Egypt was the first to describe this anomaly and warned gynecologist about this common misdiagnosis, whenever there is a uterine fundus depression on laparoscopy gynecologists should compare the depth of this depression with the depth of the dividing internal interface. Hybrid septate uterus benefit from hysteroscopic metroplasty under laparoscopic control.

The main causes are Müllerian agenesis and complete androgen insensitivity syndrome.

Midline shift measurements and imaging has multiple applications. The severity of brain damage is determined by the magnitude of the change in symmetry. Another use is secondary screening to determine deviations in brain trauma at different times after a traumatic injury as well as initial shifts immediately after. The severity of shift is directly proportional to the likeliness of surgery having to be performed. MLS also has the aptitude to diagnoses the very pathology that caused it. The MLS measurement can be used to successfully distinguish between a variety of intracranial conditions including acute subdural hematoma, malignant middle cerebral artery infarction, epidural hematoma, subarachnoid hemorrhage, chronic subdural hematoma, infarction, intraventrical hemorrhage, a combination of these symptoms, or the absence of pertinent damage altogether.

AVSDs can be detected by cardiac auscultation; they cause atypical murmurs and loud heart tones. Confirmation of findings from cardiac auscultation can be obtained with a cardiac ultrasound (echocardiography - less invasive) and cardiac catheterization (more invasive).

Tentative diagnosis can also be made in utero via fetal echocardiogram. An AVSD diagnosis made before birth is a marker for Down syndrome, although other signs and further testing are required before any definitive confirmation of either can be made.

In order to facilitate sexual intercourse, the main treatments are self-dilation methods (using intra-vaginal cylinders of increasing size) and surgical vaginoplasty to lengthen the vagina.

Self-dilation has a high success rate, estimated at 75%, and is usually the first-line treatment due to low surgical invasiveness. Overall, the complication rates are significantly lower with dilation than with vaginoplasty.

Surgery is indicated when there is inability or reluctance to perform self-dilation, or where it is performed but with failed result. One appropriate surgical variant is the "Vecchietti technique". In this procedure, an olive-shaped pressure device is pressed towards the potential vaginal space by a thread that goes through the skin, behind the urinary bladder and pubic bone and exits the skin in the hypogastrium, where it is attached to a plate that provides counter-traction. Vaginoplasty can also be performed using a skin graft or an intestinal graft. Traction vaginoplasty such as the "Vecchietti technique" seems to have the highest success rates both anatomically (99%) and functionally (96%), whereas skin graft procedures and intestinal procedures have the lowest successful outcomes (83–95%).

After vaginoplasty, available evidence suggests that continued self-dilation is needed to maintain patency in periods of coital inactivity.

Congenital heart defects are now diagnosed with echocardiography, which is quick, involves no radiation, is very specific, and can be done prenatally.

Before more sophisticated techniques became available, chest x-ray was the definitive method of diagnosis. The abnormal "coeur-en-sabot" (boot-like) appearance of a heart with tetralogy of Fallot is classically visible via chest x-ray, although most infants with tetralogy may not show this finding. Absence of interstitial lung markings secondary to pulmonary oligaemia are another classic finding in tetralogy, as is the pulmonary bay sign.

A chest x-ray will be given to determine the size of the heart and the blood vessels supplying blood to the lungs.

A chest radiogram can be given to a patient to determine:

- Pulmonary plethora: the test will help to determine if there is a left-to-right shunt meaning the blood is flowing from the left atrium to the right through a hole between the two atria.

- Mild left atrial enlargement: the test will help to determine if the left atrium is enlarged due to alternate blood flows

- Right ventricular enlargement: the test will help to determine if the ventricle is enlarged due to a surge of blood above normal or if the ventricle is having to work harder than normal to pump blood out of the ventricle.

- Pulmonary artery enlargement: the test will help to determine if there is a large volume of blood in the pulmonary veins and arteries than normal

- Mitral Valve calcification late in life: the test will help to determine if the mitral valve or flaps are becoming hardened and losing their floppiness.

- pulmonary vascular congestion, marked left atrial enlargement: the test will help to determine if there is a sign of MS and small ASD and how severe both are.

A VSD can be detected by cardiac auscultation. Classically, a VSD causes a pathognomonic holo- or pansystolic murmur. Auscultation is generally considered sufficient for detecting a significant VSD. The murmur depends on the abnormal flow of blood from the left ventricle, through the VSD, to the right ventricle. If there is not much difference in pressure between the left and right ventricles, then the flow of blood through the VSD will not be very great and the VSD may be silent. This situation occurs a) in the fetus (when the right and left ventricular pressures are essentially equal), b) for a short time after birth (before the right ventricular pressure has decreased), and c) as a late complication of unrepaired VSD. Confirmation of cardiac auscultation can be obtained by non-invasive cardiac ultrasound (echocardiography). To more accurately measure ventricular pressures, cardiac catheterization, can be performed.

Besides a physical examination, the physician will need imaging techniques to determine the character of the malformation: gynecologic ultrasonography, pelvic MRI, or hysterosalpingography. A hysterosalpingogram is not considered as useful due to the inability of the technique to evaluate the exterior contour of the uterus and distinguish between a bicornuate and septate uterus.

In addition, laparoscopy and/or hysteroscopy may be indicated.

In some patients the vaginal development may be affected.

To treat a septal haematoma it is incised & drained to prevent avascular necrosis of the septal hyaline cartilage which depends on diffusion of nutrients from its attached nasal mucosa. Small hematomas can be aspirated with a wide-bore needle. Large hematomas are drained by an incision parallel to nasal floor. Systemic antibiotics are given after the incision and drainage to prevent local infection.

Diagnosis depends on the clinical scenario. However, karyotyping is an essential test for diagnosis.

d-TGA can sometimes be diagnosed in utero with an ultrasound after 18 weeks gestation. However, if it is not diagnosed in utero, cyanosis of the newborn (blue baby) should immediately indicate that there is a problem with the cardiovascular system. Normally, the lungs are examined first, then the heart is examined if there are no apparent problems with the lungs. These examinations are typically performed using ultrasound, known as an echocardiogram when performed on the heart. Chest x-rays and electrocardiograms (EKG) may also be used in reaching or confirming a diagnosis; however, an x-ray may appear normal immediately following birth. If d-TGA is accompanied by both a VSD and pulmonary stenosis, a systolic murmur will be present.

On the rare occasion (when there is a large VSD with no significant left ventricular outflow tract obstruction), initial symptoms may go unnoticed, resulting in the infant being discharged without treatment in the event of a hospital or birthing center birth, or a delay in bringing the infant for diagnosis in the event of a home birth. On these occasions, a layperson is likely not to recognize symptoms until the infant is experiencing moderate to serious congestive heart failure (CHF) as a result of the heart working harder in a attempt to increase oxygen flow to the body; this overworking of the heart muscle eventually leads to hypertrophy and may result in cardiac arrest if left untreated.

Although there are several classifications for VSD, the most accepted and unified classification is that of Congenital Heart Surgery Nomenclature and Database Project.

The classification is based on the location of the VSD on the right ventricular surface of the inter ventricular septum and is as follows:

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.
