Infundibulo neurohipofisitis linfoplasmocitaria con compromiso quiasmatico e hipotalamico. Presentacion de un caso / Linfoplasmocitary infundibulohipophisitis with chiasmal and hypothalamic involvement. Case presentation

Objective: to present a 38 year old female patient, with central diabetes insipidus, panhipopituitarims, and severely impaired vision. Description: magnetic resonance imaging demonstrated a large mass involving the hypothalamus, infundibulum, optic nerves, and chiasm. Intervention: at surgery the optic pathways were found to be grossly involved within the inflammatory mass. Histological examination demonstrated anonspecific, mixed inflammatory infiltrate, composed predominantly of lymphocytes and plasma cells. She responded dramatically to dexamethasone, with mass reduction on serial imaging studies and vision improvement. In addition, she received hormone replacement therapy. Infundibulohypophisitis is a rare disease. Surgical biopsy and dexamethasone were an effective treatment
