Cerebral proliferative angiopathy (CPA) is a rare vascular abnormality that is distinct from classical brain arteriovenous malformations. This article describes a case of cerebral hemorrhage caused by CPA and successful treatment using two different endovascular techniques.
Cerebral proliferative angiopathy (CPA) is a rare vascular abnormality characterized by transdural supply, stenoses of feeding arteries, and intermingled normal brain parenchyma in abnormal vessels. CPA is often regarded as a separate entity from classical brain arteriovenous malformations in angioarchitecture, natural history, clinical presentation, and treatment. Bleeding from CPA is uncommon, but once bleeding occurs, the risk of rebleeding is high. Herein, we describe a case of cerebral hemorrhage caused by CPA. We performed two different endovascular treatments: partial embolization with glue for a ruptured aneurysm and coil embolization for an unruptured growing aneurysm. To our knowledge, this is the first report of serial endovascular treatments for hemorrhagic CPA that included a ruptured aneurysm and a growing unruptured aneurysm.
