Intravascular papillary endothelial hyperplasia at the fissura orbitalis superior: a case report.

We report on a 27-year-old female suffering from headaches and nervus abducens paresis. Operation surprisingly revealed an intracranial intravascular papillary endothelial hyperplasia (IPEH) at the left fissura orbitalis superior visualized angiographically as a widening of the left ophthalmic artery. Clinical symptoms completely disappeared after the operation. IPEH is considered to be a rare benign lesion. Intracranial location has been reported only four times. The present case is the first IPEH described at the fissura orbitalis superior.
