We present the unusual case of a 33-year-old woman who presented with a 2 year history of amenorrhoea and an expanding sellar lesion. Initial MRI revealed a lesion in the pituitary fossa, thought to be a pituitary adenoma. One year later, the lesion had enlarged by 5mm, with associated enhancement of the dura of the planum sphenoidale and pituitary stalk. Histopathology revealed a lymphocytic and plasma cell inflammatory infiltrate suggestive of lymphoplasmacytic hypophysitis associated with immunoglobulin G4.

A 72-year-old man presented with several months of weakness, poor appetite, and depressed moods. Laboratory tests indicated central hypocortisolism, hypothyroidism and hypogonadism, and mild hyperprolactinemia. Imaging indicated a homogenously enhancing solid suprasellar mass inseparable from the hypothalamus and contiguous with a thickened proximal infundibulum.

Background/objective: Antineutrophil cytoplasmic antibody (ANCA) associated vasculitis is a rare small vessel vasculitis that can cause pituitary hypophysitis. Hypophysitis is difficult to treat, often requiring high doses of glucocorticoids with frequent flaring as glucocorticoids are tapered. We present a case of ANCA vasculitis involving the pituitary gland successfully treated with rituximab.

Summary: We report a rare case of biopsy-proven isolated immunoglobulin G4 (IgG4)-related hypophysitis and Rathke's cleft cyst (RCC) presenting as panhypopituitarism. A 54-year-old Caucasian female presented with symptoms of slurred speech, altered mental status, polyuria and polydipsia and was found to have panhypopituitarism. Brain MRI showed a suprasellar mass with suspected intralesional hemorrhage.

Lymphocytic hypophysitis (LYH) is a rare inflammatory disease in which lymphoplasmacytic infiltration of the pituitary gland can potentially lead to panhypopituitarism. This entity was first recognized in 1962 by Goudie and Pinkerton. We report the case of a 36-year-old nonpregnant female operated for a presumed nonsecreting pituitary adenoma.
