Rapid Brain Shift with Remote-Site Haemorrhage after Arachnoid Cyst Excision: Treatment Dilemmas.

Sylvian arachnoid cysts pose considerable management dilemmas. Surgical options include cyst fenestration, either endoscopically or microsurgically, and cysto-peritoneal shunt. One of the rare complications after rapid decompression of the arachnoid cysts is haemorrhage in the surrounding brain as well as in remote areas. We describe a case of multiple remote-site intra-parenchymal haemorrhage as a rare complication after surgical decompression of a sylvian fissure arachnoid cyst.
