A 43-year-old female was admitted showing abnormal feeling in the left eye region. Left facial hypesthesia and quadrantic hemianopsia of left eye were the detectable neurological findings. A plain skull x-ray film revealed a double floor and dilatation of the sella turcica. The tomogram of the sella turcica demonstrated a dilatation of superior orbital fissure. Caudocranial projection revealed a dilatation of foramen ovale. A computerized tomography scan revealed a slightly high density tumor which was enhanced slightly with a contrast medium in the parasellar region and left middle fossa. Carotid angiogram demonstrated the displacement of the left carotid fork to the upper and lateral direction. However, no other sign was found. The sinogram of cavernous sinus clearly demonstrated an indentation in the left cavernous sinus. The endocrinological tests were almost normal except for hyperprolactinemia. A trigeminal neurinoma and a pituitary tumor were suspected. The tumor was totally removed and was histologically diagnosed as a cavernous angioma. At operation it seems to be extracerebral in the middle fossa and originate in the cavernous sinus. Diagnostic problems endocrine findings and the origin are discussed.
