Gray matter heterotopia
Gray matter heterotopia (singular heterotopion) is a neurological disorder caused by clumps of grey matter being located in the wrong part of the brain. It is characterized as a type of cortical dysplasia. The neurons in heterotopia appear to be normal, except for their mislocation; nuclear studies have shown glucose metabolism equal to that of normally positioned gray matter. The condition causes a variety of symptoms, but usually includes some degree of epilepsy or recurring seizures, and often affects the brain’s ability to function on higher levels. Read more…

Fibrous dysplasia is a developmental anomaly that can affect any bone in the body. The skull and facial bones are the affected sites in 10-25% of patients with monostotic fibrous dysplasia and in 50% of patients with polyostotic fibrous dysplasia.
MR imaging characteristics of fibrous dysplasia do not share the distinctive features seen on radiography and CT. In fact, the MR imaging appearances of fibrous dysplasia often resemble that of tumors. Read more…
Venous angioma
Venous angiomas, also known as Venous vascular malformations or developmental venous anomalies (DVA), represent congenital anatomically variant pathways in the normal venous drainage of an area of the brain.

A subdural hygroma is a subdural body of cerebrospinal fluid (CSF), without blood. Most subdural hygromas are believed to be derived from chronic subdural hematomas. It is commonly seen in elderly patients after minor trauma but can be seen in children after an infection. One of the common causes of subdural hygroma is a sudden decrease in pressure by ventricular shunting. This can lead to leak of CSF into the subdural space especially in cases with moderate to severe brain atrophy. In these cases the symptoms such as mild fever, headache, drowsiness and confusion can be seen, which are relieved by draining this subdural fluid.

Lateral medullary syndrome (also called Wallenberg syndrome and posterior inferior cerebellar artery syndrome) is a disease in which the patient has a constellation of neurologic symptoms due to injury to the lateral part of the medulla in the brain, resulting in tissue ischemia and necrosis.
