New onset panhypopituitarism on anti-cancer immune modulator with hypophysitis as side effect; rule out mets or other causes of pituitary failure There is heterogeneous enhancement of the pituitary gland without significant enlargement of the gland or the pituitary infundibulum. The posterior pituitary bright spot is intact. There is no evidence of mass lesions. The optic apparatus and cavernous sinuses are intact. The imaged intracranial structures are unremarkable.
Heterogeneous enhancement of the pituitary gland may represent treatment-related necrotizing hypophysitis.
