Intraoperative supratentorial epidural haematoma during removal of a huge posterior fossa dermoid cyst.

Epidural haematomas may occur following cranial operations, and most of them are located near the craniotomy or burr-hole areas. There are very few cases of supratentorial epidural haematoma following the resection of giant tumours located in the posterior fossa. In this case report, we present a patient who developed an acute left temporoparietal epidural haematoma in the perioperative period during the excision of a huge dermoid cyst in the posterior fossa.
