Remote Cerebellar Hemorrhage after Removal of a Supratentorial Glioma without Perioperative CSF Loss: A Case Report

摘要

A 44-year-old man presented with the rare complication of remote cerebellar hemorrhage (RCH) after removal of a supratentorial glioma without the loss of a large volume of cerebrospinal fluid (CSF). He presented with severe headache, nausea, and vomiting for a few days, then he developed neurological deterioration including progressive disturbance of consciousness and left hemiparesis. Magnetic resonance imaging revealed a large tumor with intratumoral hemorrhage in the right frontal lobe that led to subfalcial and transtentorial herniation. The tumor was removed en bloc without excessive loss of CSF throughout the perioperative period. Although the level of consciousness remained unchanged from the preoperative level and no new neurological deficit was detected, routine postoperative computed tomography showed a bilateral RCH. Careful conservative therapy was provided and follow-up computed tomography demonstrated no further progression of hemorrhage. Compensatory acute engorgement of venous sinuses derived from the rapid decrease in intracranial pressure that occurred due to removal of the huge tumor might have caused cerebellar hemorrhagic venous infarction.
