What is a pituicytoma?
- Pituicytoma is a rare tumor of the sellar and suprasellar regions (< 0.5% of sellar tumors) originating from specialized glial cells in the neurohypophysis and the infundibulum.
- These slow growing, benign stalk tumors generally occur in females > males and in the fourth to sixth decades of life.
- Patients typically present with mass effects (e.g., headaches, vision loss, and hypopituitarism). Surgical resection is usually the first-line therapy for pituicytomas.
