Abstract

A sixty-three year old woman presented with sudden onset of dystonic twitching of the extremities and repeatedly downgrading of consciousness in the midnight. She had no history of medical illness in the past but had been suffered from fatigue recently before the onset of the attack. At admission she was neurologically free including neuro-ophthalmologic examination. MRI showed a high signal T1WI mass in the sella protruding into the suprasellar cistern. Hormonal study revealed low value of T3, T4, LH and FSH. Under the impression of pituitary apoplexy she underwent operation via transcranial route. When the protruding diaphragma sellae was opened, milkish pus spilled out. The thick capsule was biopsied and pus was sent for the study. The results of Gram staining and culture were both negative but pathologic report of the specimen was high infiltration of lymphocytes with few polymorphs.
