ABSTRACT
Cystic lesions of the parasellar region are not uncommon and masquerade as a tumor both radiologically and clinically. True intrasellar arachnoid cysts are rare lesions and can easily be confused with intrasellar pituitary neoplasms, craniopharyngiomas, Rathke's cleft cysts, or even empty sella. The preoperative and peroperative distinction is obviously important because of the different treatment strategies and different prognosis. A 44-years-old woman with presenting symptoms of headache and decreased visual acuity with the initial diagnosis of either Rathke's cleft cyst or intrasellar arachnoid cyst is reported. The evaluations for differential diagnosis, commonly encountered pathological entities, treatment modalities and pathogenesis of intrasellar arachnoid cysts were discussed.
