CT-angiographic correlation in Sturge-Weber syndrome.

Sturge-Weber syndrome in its classic form can be easily diagnosed by CT. However, in the absence of the typical gyral calcification, the diagnosis can be missed on CT. Identification of the intracranial angiomatosis and the associated thrombosis, and thus the diagnosis, require angiography. Computed tomographic and angiographic findings in a case of Sturge-Weber syndrome with unusual clinical features is described.
