ABSTRACT
Intrasellar arachnoid cysts are rare entities. High index of suspicion and precise radiological evaluation are the cornerstone for appropriate diagnosis and treatment. We present a symptomatic case of a sellar cystic lesion in a 52-year-old lady, who had complaints of decreased vision associated with diplopia of three months duration. Clinical evaluation showed bitemporal hemianopia. Magnetic Resonance Imaging (MRI) of brain revealed features of sellar arachnoid cyst with the intracystic component similar to cerebrospinal fluid (CSF). She underwent endoscopic transnasal transsphenoidal excision of lesion. Her visual symptoms improved well on subsequent follow up.However infrequent, sellar arachnoid cyst should be borne in mind as differential diagnosis for any cystic sellar lesions, as they can mimic pituitary adenomas, either by impairment of pituitary hormonal function or by exerting pressure effects on optic chiasma. Evaluation modalities, therapeutic challenges and literature review are presented in this case report.
