[Balance disorder and subacute hydrocephalus due to haemorrhage in a cerebral cavernous malformation].

A 58-year-old man presented with a balance disorder, followed by progressive memory disturbance, urinary incontinence and vomiting. MRI of the brain revealed multiple cavernous malformations, with recent haemorrhage from one of them, in the brainstem, causing a hydrocephalus. After treatment for the hydrocephalus, the symptoms resolved quickly. Cerebral cavernomas may cause epileptic seizures, haemorrhaging and progressive neurological deficits. Diagnosis is on the basis of the typical MRI pattern of a hyperintense core, surrounded by a hypointense rim of old blood. Treatment consists of surgery if the lesion is easily accessible and can be completely removed. Other options are gamma-knife surgery, stereotactic radiotherapy and conservative treatment.
