Cerebral Proliferative Angiopathy in a Child, Five Years after an Intraventricular Hemorrhage and Negative Catheter Angiography

Abstract

Cerebral proliferative angiopathy (CPA) is a rare cerebrovascular disease comprised of a diffuse network of blood vessels, often spread over several lobes. Due to the presence of normal brain tissue within the malformation, complete resection is not desirable. Several imaging characteristics help to distinguish CPA from brain arteriovenous malformations. We report the case of a patient diagnosed with CPA five years after a spontaneous intraventricular hemorrhage and an initial negative angiogram. Teaching Point: The radiologist should be able to differentiate CPA from brain AVM to prevent potentially harmful treatment.
