A Rare Pituitary Tumor

Sellar-suprasellar masses, with diverse origins ranging from infiltrative to neoplastic processes, are frequently encountered in endocrinology clinics. Evaluation involves a detailed history, hormone analysis, and imaging of the hypothalamic-pituitary axis. However, overlapping hormonal and imaging features can complicate diagnosis, often necessitating confirmation through tissue biopsy. Pituicytoma, a rare sellar tumor mimicking other masses biochemically and radiologically, exemplifies this challenge. These are benign intracranial neoplasms with characteristic bipolar spindle-shaped astrocytic cells organized in fascicular or storiform patterns with specific immunohistochemistry. The current case is of an elderly postmenopausal woman with a history of hypertension who presented with recurrent headaches and transient vision loss in the left eye. Imaging studies revealed a suprasellar mass, which was biopsied and diagnosed on histopathological examination as a pituicytoma. This case highlights the importance of considering less common etiologies when encountering such presentations.
