Lymphocytic hypophysitis (LH), an autoimmune mediated chronic inflammation of the pituitary gland, is uncommon in the elderly population greater than 70 years old. It most commonly occurs in peripartum women and classically presents with mass-effect symptoms, hyperprolactinemia, or with symptoms of adenohypophysial or neurohypophysial involvement. We report a case of an elderly female who presented with headaches, visual defects, panhypopituitarism, and a sellar mass thought to be a non-functioning pituitary macroadenoma. On surgical pathology the diagnosis of LH was made. In a comprehensive literature search, we have found only sixteen cases of LH in the elderly. A comparison of the clinical differences between the pediatric, adult, and elderly populations with LH revealed notable differences between the clinical presentations and hormonal deficiencies present in the pediatric versus the adult and elderly populations. A much larger portion of adults and the elderly present with headache and visual disturbances, while a majority of the pediatric population presents with diabetes insipidus and growth hormone deficiency. Adults and elderly with LH have a much higher association with autoimmune disease than children. There was no gender predilection found in the elderly population, which is a notable difference from the adult population in which female cases of LH are much more common.
