Abstract
Over the past 9 years, we have experienced 8 cases of intracerebral venous angiomas, which were identified angiographically or histologically. We analyzed their clinical symptoms, neuroradiological findings, clinical courses, and outcomes.
There were 4 males and 4 females whose ages ranged from 19 to 79 years (mean: 49.4 years). Initial clinical symptoms were epilepsy (3 cases), hemiparesis due to intracerebral hemorrhage (1 case), and headache (1 case). Three cases were incidentally found. The angiomas were located in the frontal lobe in 5 cases, in the cerebellum in 2 cases, and in the parietal lobe in 1 case. CT scans without contrast enhancement revealed the sites of venous angiomas as high density areas (nodules) in 6 cases out of 7 examinations. Contrast-enhanced CT scans in 8 cases demonstrated highly enhanced angioma sites 7 cases. Angiography demonstrated typical (characteristic) caput medusae in 7 out of 8 cases. No angioma was angiographically found in one patient who presented intracerebral hemorrhage. MRI scan was done in one case. In T1WI, the drainer showed a low intensity, and in T2WI, the nidus was seen as a high intensity area and the drainer showed a low intensity. During this observation period between 4 months and 6 years, one patient out of the 8 died due to senility but the remaining seven were without further epilepsy and stroke attacks. Therefore, the clinical course of intracerebral venous angioma is considered to be benign. Surgical treatment should be considered in patients who present intracerebral hematoma and have typical venous angioma seen with CT and angiography. Otherwise, conservative therapy is the treatment of choice.
