[Intrasellar epidermoid cyst. Case report].

  A rare case of an intrasellar epidermoid cyst with ophthalmologic and endocrinological disorders is reported.  A 54-year-old male complained of decreased visual acuity and visual field defects. On admission, bitemporal hemianopsia and panhypopituitarism were revealed. Computed tomography (CT) demonstrated a homogeneous low density area in the sellar region. The margin of the low density area was slightly enhanced. The low density area was clearly distinguished from the cerebrospinal fluid space in the metrizamide CT cisternography. The mass lesion was totally removed by the transsphenoidal approach. Histological examination of the surgical specimen showed that the cyst wall consisted of stratified squamous epithelium with keratinization and confirmed the diagnosis of epidermoid cyst.
