Background:
Inflammatory pseudotumor of the pituitary is a very rare nonneoplastic lesion. We describe a case of a patient with past history of lymphocytic meningitis.
Case Description:
A 32-year-old man presented with polyuria, polydipsia, anorexia, abdominal discomfort, and panhypopituitarism. He had 2 episodes of lymphocytic meningitis in the last two years. Magnetic resonance image (MRI) disclosed a sellar and suprasellar mass with extension to the pituitary stalk. The patient underwent transnasal-transsphenoidal surgery to remove the lesion. Histopathological findings revealed mixed inflammatory cells composed mainly of lymphocytes, macrophages and extensive fibrosis.
Conclusions:
Inflammatory pseudotumor of the pituitary, although rare, should be included in the differential diagnosis of a sellar and suprasellar mass.
