Ruptured intracranial dermoid cyst.
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. Th ey are not to be confused with an epidermoid cyst, which contains only squamous...
متن کاملRuptured intracranial dermoid cyst.
Intradural dermoids are rare congenital tumors representing approximately 0.05% of all intracranial lesions. These benign tumors have a typical appearance on CT and MR due to their lipid components. 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 کاملNasal dermoid with intracranial extension.
Nasal dermoids are rare congenital anomalies, which usually present in early childhood as a midline nasal mass that requires surgical management. It is important to rule out any intracranial extension before subjecting the patient to surgery. We describe a case of nasal dermoid with intracranial extension. The embryology of the formation of the nasal dermoid, cyst and sinus, with the role of CT...
متن کاملTraumatic rupture of an intracranial dermoid cyst
Intracranial dermoid cysts are congenital tumors of ectodermal origin. Rupture of these cysts can occur spontaneously, but rupture in association with trauma is reported infrequently. The diagnosis of rupture is made by the presence of lipid (cholesterol) droplets in the subarachnoid spaces and ventricles. Nonenhanced CT of the head demonstrates multiple foci of low attenuation that correspond ...
متن کاملIntracranial dermoid cyst rupture-related brain ischemia
RATIONALE Spontaneous rupture of intracranial dermoid cyst is a rare but serious clinical event that can result in cerebral ischemia. Cerebral vasospasm and vasculitis are considered as potential mechanisms of dermoid cyst rupture-related cerebral ischemia. However, the hemodynamic mechanisms between cerebral ischemia and dermoid cyst rupture are not well known. PATIENT CONCERNS A 55-year-old...
