Intracranial dermoids rarely rupture. They are associated with significant risk of morbidity and mortality when they rupture. The rupture within the ventricle is further rarer. Case report: We present a case of intraventricular rupture of a dermoid cystic tumor along with dissemination of subarachnoid fat. The diagnosis was made on CT scan and MRI imaging. The patient died in few days from chemical meningitis. Intracranial dermoid cystic tumors account for __ampersandsignlt;1% of all intracranial masses. Dermoids are nonneoplastic, congenital ectodermal inclusion cysts that contain varying amounts of ectoderm derivatives to include apocrine, sweat, and sebaceous cysts as well as hair follicles, squamous epithelium, and possibly teeth. They are separate from an epidermoid cyst or Teratomas. Teratomas are true neoplasms that contain tissue from all three embryonic germ cell layers (1).
