Abstract

Remote cerebellar hemorrhage (RCH) is a rare complication of neurosurgical procedures and is characterized by a typical bleeding pattern defined as the “zebra sign.” Only few cases of RCH have been reported in the English literature, and its pathophysiology remains unclear. In this report, we present the cases of three patients with RCH after three different procedures: burr-hole trephination and chronic subdural hematoma evacuation of bilateral cerebral convexity with subsequent subdural drain insertion, lumbar drainage for cerebrospinal fluid divergence for thoracic endovascular aortic repair, and combined bypass surgery for moyamoya disease.
