 Abstract

- A 64-year-old Korean woman presented with a 3-week history of severe headache and ocular pain. Her brain MRI showed a cystic pituitary mass compressing the optic chiasm. A hormonal study revealed anterior pituitary insufficiency and a slightly increased prolactin level. We performed a transsphenoidal resection of the pituitary mass. A pathological examination revealed the presence of a heavy inflammatory infiltrate, composed of lymphocytes and plasma cells, and destruction of the adenohypophysial structures. Five months after surgery, her hormonal levels had nearly normalized, without hormone replacement therapy. A follow-up MRI showed no recurrence. We conclude that lymphocytic hypophysitis should be included in the differential diagnosis of pituitary mass at any age. We discuss the features that can help to make a preoperative differential diagnosis, and selection of the appropriate treatment.

Abstract
PDF
- Anticonvusant therapy with any of several agents, especially phenytoin, phenobarbital, and primidone causes disturbances in bone mineral metabolism. Anticonvulsants stimulate the hepatic microsomal mixed-oxidase enzymes and hence increase the rate of clearance of vitamin D and its metabolism. The severity of clinical manifestations in any given individual appears to be a function of the combined effects of variety of factors including drug type and total drug dose, dietary vitamin D intake, sunlight exposure, and physical activity level. We report a case of osteomalacia associated with long term carbamazepine therapy in a 21-year-old male with less exposure to sunlight.
