Recurrent Intraventricular Haemorrhage in Cerebral Proliferative Angiopathy - A Case Report and Review of the Literature.

ABSTRACT

Cerebral proliferative angiopathy (CPA) is an entity distinct from that of classical arteriovenous malformations. As such, few reports have considered the long-term follow-up of patients with hemorrhage in CPA. Accordingly, herein the authors present a case of recurrent hemorrhage in CPA with 32 years of follow-up and in so doing summarize the literature of hemorrhagic cases in CPA. A 19-year-old presented with focal awareness seizures and diagnostic work-up revealed a left hemispheric vascular lesion. The patient presented again with intracranial hemorrhage at ages 28, 43 and 51. Angioarchitectural workup revealed intermingled brain parenchyma between vascular spaces, absence of dominant feeders and a clear nidus consistent with CPA. The size and diffuse nature of the lesion deemed it inoperable. Given our case and review of the literature it is apparent that CPA has a high risk of re-hemorrhage in the rare event that hemorrhage does occur.
