Lymphocytic hypophysitis is a rare inflammatory disease of the pituitary gland that is being increasingly recognized as a cause of hypopituitarism. This condition may be due to an autoimmune pituitary destruction which usually occurs in young women during pregnancy or in the immediate postpartum period. We describe a case of cystic pituitary mass in a thirty-eight year-old woman presenting with nausea, vomiting, cold intolerance, blurring of vision and the presence of disagreeable odors for a one-month period. She had secondary amenorrhea and galactorrhea for three months. Combined anterior pituitary stimulation test confirmed the diagnosis of hypopituitarism. Magnetic resonance imaging scan with enhancement showed a huge cystic sellar mass with suprasellar extension and thickening of the pituitary stalk. Transsphenoidal exploration was performed with preoperative diagnosis of pituitary macroadenoma with cystic necrosis. Histological examination revealed lymphocytic hypophysitis characteristic of diffuse, dense lymphocytes and plasma cells infiltration with surrounding interstitial reactive fibrosis. Postoperatively, the patient's olfactory function returned to normal but combined anterior pituitary stimulation test showed persistence of hypopituitarism with mild hyperprolactinemia. Prednisolone, thyroxine and estrogen replacements were started and clinical symptoms were much improved. In summary, we report an extremely rare case of a woman with cystic lymphocytic hypophysitis with cacosmia and hypopituitarism, confirmed by histological examination.

Lymphocytic hypophysitis, an autoimmune mediated chronic inflammation of the pituitary gland, is uncommon in children.(1) The usual presentation is with symptoms secondary to pressure from the enlargement of the gland itself and or impairment of pituitary hormones of varying degrees, in conjunction with a sellar mass.( 2,3) In 80% of cases, partial or panhypopituitarism is present with approximately 75% of cases having multiple hormonal deficiencies.(2) We report the case of a prepubertal female who presented with cyclical vomiting, as her initial symptom of lymphocytic hypophysitis which resolved promptly after pituitary biopsy. This case suggests that cyclical vomiting can be a symptom associated with lymphocytic hypophysitis. Therefore, it should be considered in the differential diagnosis of any child presenting with cyclical vomiting.

Lymphocytic hypophysitis is an inflammatory /autoimmune disorder that primarily involves the pituitary gland and the pituitary stalk. The common clinical presentations include headache, nausea, vomiting, fatigue, features of hypopituitarism and diabetes insipidus as well as diplopia, orbital pain and bitemporal hemianopia. We report a case of lymphocytic hypophysitis which presented as hemichorea. Neuroimaging showed a mass in the sella tursica region which, on histopathological examination was suggestive of lymphocytic hypophysitis. After excision of this mass, patient showed marked improvement in his symptoms albeit he developed panhypopituitarism. The patient was treated with pituitary hormonal replacement therapy and is currently asymptomatic.
