In this podcast episode, Dr. Vilanilam discusses “Cerebral Proliferative Angiopathy: Imaging Spectrum and Diagnostic Insights,” by first author Rai. Cerebral proliferative angiopathy is a rare cerebrovascular malformation that can mimic an arteriovenous malformation but has a fundamentally different vascular architecture and underlying physiology. This comprehensive review of 75 studies and 153 patients highlights its characteristic multimodal imaging features, including a diffuse vascular network intermingled with normal brain, absence of a compact nidus or dominant arterial feeders, frequent transdural recruitment, relatively limited early venous drainage, and evidence of chronic hypoperfusion. Dr. Vilanilam reviews the key CT, MRI, perfusion, and...
