Dizziness and giddiness, intractable vertigo, evaluate for structural lesion. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a 7 mm T2 hyperintense focus in the right superior paramedian cerebellum with associated susceptibility changes and subtle enhancement consistent with cavernoma. There is an associated developmental venous anomaly.The brain parenchyma and pituitary gland appear unremarkable. There is a probable small subcentimeter pineal cyst. Otherwise, there is no abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.
1. 7 mm cavernous malformation with associated developmental venous anomaly in the right superior paramedian cerebellum.2. No evidence of acute acute ischemia or intracranial mass.
