RESUMO
We report a case of intrasellar arachonoid cyst with extension to the sphenoid sinus, which is a very uncommon lesion. Preoperatively, we studied the PNS CT & Brain MRI and these images showed a large cyst in the widened sellar turcica with extension to the sphenoid anterior wall. We planned endoscopic surgery via transnasal-transphenidal approach. The endoscopic surgery was performed with no complication. We reviewed the literature and discussed the treatment of the intrasellar arachnoid cyst.

Primary amenorrhea due to intrasella arachnoid cyst is a very rare disease and require careful and frequent evaluation because may produce intracranial hemorrhage, elevated intracranial pressure and rapid expansion. Surgical intervention is needed only when visual disturbance, hypopituitarism or enlarging lesion is shown. Thus, we present a case of primary amenorrhea due to intrasella arachnoid cyst which was resected through the transsphenoidal approach.

A case of a large symptomatic intrasellar arachnoid cyst with suprasellar extension is reported. A 59-year-old woman was admitted because of headache and visual field defect caused by optic nerve compression. Magnetic resonance imaging showed a large intrasellar cyst extending into the suprasellar cistern, with compression of optic nerves. Transsphenoidal approach with cystectomy was performed. Histological study revealed that the cyst wall was composed of dense collagenous fibrous tissue and epithelial cells. The pathophysiology and the MRI finding of intrasellar arachnoid cysts are discussed.

A rare case of intrasellar arachnoid cyst is reported. The patient was a 55 years old woman presented with 8 years history of blurred vision, headache and bitemporal visual field cuts aggravated for last 4 months. The pathophysiology and the CT and MRI findings being useful in the differentiation of cystic sellar masses were discussed.
