An Intracranial Extradural Dermoid Cyst Presenting with Two Dermal Sinuses and an Abscess in a Child

a case of intracranial dermoid cyst presenting like an epidermoid cyst in ethmoidal region

dermoid cyst is a tumor arises due to embryogenesis impairment. it accounts for less than 0.3 percent of all intracranial masses. a 35 years old man presented with a tonic clonic seizure without any significant past history of seizure. physical examination and imaging propounded epidermoid cyst as diagnosis. the patient had a craniotomy and cyst was totally removed. operative findings and histo...

Traumatic 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 ...

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...

Ruptured 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...
