Remote cerebellar hemorrhages

Abstract

Remote cerebellar hemorrhage is a rare complication of a variety of neurosurgical procedures, mainly supratentorial craniotomies, which occur frequently distant to the site of surgery. The precise mechanisms by which remote cerebellar hemorrhage occurs are unknown; however, two facts are known: it is of venous origin and is the result of intra- and postoperative loss of cerebrospinal fluid. Non- enhanced CT is the modality of choice and shows superficial linear hyperdense bleeds in the superior surface of the cerebellar hemispheres. Although MRI is more sensitive than CT in detection of small hemorrhages, this does not affect treatment, and therefore, MRI is not the first modality of choice to image patients in which this condition is suspected.
