AbstractVarious mixed associations between arteriovenous malformations, cavernous malformations, developmental venous anomalies, and capillary telangiectasias have been described, and a common pathophysiologic event has been suggested to be present, although it is yet to be elucidated. We depict herein the imaging features of a patient who presented with a spontaneous cerebellar hemorrhage, in whom radiologic studies demonstrated a pontine telangiectasia, a brainstem/cerebellar developmental venous anomaly, and a cerebellar proliferative angiopathy. This unique, not previously reported combination of lesions shows that the spectrum of mixed vascular malformations continues to expand. A pathophysiologic mechanism related to the angiogenesis seen in these malformations is also hypothesized.Copyright © 2018 Elsevier Inc. All rights reserved.
