I ntracranial dermoid cystic tumors account for <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.

The complication caused by rupture are the spillage of the fatty material into the cerebrospinal fluid. We report a case of a ruptured dermoid cyst showing fat/fluid levels in both side ventricles a...

متن کاملRuptured Intracranial Dermoid and the Chemical Shift Artifact
Intracranial dermoids are rare congenital conditions accounting for 0.04%–0.6% of all intracranial tumors and are derived from ectopic cell remnants incorporated into the neural tube. They are composed fibrous stratified squamous epithelium capsule, enclosing thick viscous greenish‐brown fluid. This fluid contains lipid metabolites, cholesterol crystals, whorls of hair, calcified areas, and dec...
