Non-traumatic haemorrhage in an arachnoid cyst and ipsilateral subdural hematoma

Abstract

A case of haemorrhage into an arachnoid cyst with no history of injury is reported. The patient had an associated subdural hematoma also. Arachnoid cysts are incidentally detected on neuroimaging. Hemorrhage into the cyst is a rare complication following head trauma. Subdural hygromas and hematomas are also rare associations and less than 30 cases of arachnoid cysts with spontaneous hemorrhage are reported in literature.
