The radiological diagnosis of cerebral venous angioma: cerebral angiography and computed tomography

Abstract

The angiographic and CT findings in seven cases of cerebral venous angioma are presented and analyzed. Two cases were also examined with dynamic CT. The radiological literature on the subject is reviewed and a new classification of cerebral venous angioma based on its pattern of drainage is proposed. It is concluded that with the use of thin slices and coronal cuts both the angioma and its pattern of venous drainage can be identified on CT in a high proportion of cases. In addition, with dynamic CT the specificity of CT in diagnosing cerebral venous angioma may further increase.
