Pituicytoma

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.
