Abstract

|
|
Objectives: Arachnoid cysts are a relatively rare pathological entity, and a suprasellar arachnoid cyst is quite rare. We report on an extremely rare case of a suprasellar arachnoid cyst associated pituitary adenoma and discuss the possible pathogenesis.
Clinical Presentation: A 24-year-old man was admitted to the hospital with a history of headache, visual field defect, gait disturbance, syncope, and urinary incontinence. Computed tomography showed severe hydrocephalus. Preoperative magnetic resonance images revealed a mass lesion in the sella turcica with suprasellar extension and a coexisting large supra- and parasellar cyst. Transcranial surgery was performed for the removal of the tumor mass and cyst. Ventricle size normalized after the operation. He exhibited an uneventful recovery without neurologic deficits or endocrinologic abnormalities.
Conclusion: We present clinical, radiological, and histopathological findings and discuss the possible pathogenesis of a suprasellar arachnoid cyst associated pituitary adenoma.
