title: A relapsing remitting lymphocytic hypophysitis.
abstract: Lymphocytic Hypophysitis is a rare autoimmune disease of the pituitary presenting mainly with features of a mass lesion and loss of pituitary function. Its course is quite unpredictable and its treatment is still controversial as experience in the field remains scarce. We describe a 45 year-old woman with a history of recurrent fever and meningeal symptoms who was referred 3 years later to our department for pituitary insufficiency. Hormonal studies revealed an anterior pituitary deficiency and autoimmune thyroiditis. Pituitary hypertrophy as evidenced by magnetic resonance imaging showed complete regression upon hydrocortisone substitution therapy. Two years later, fever and meningeal symptoms recurred as well as pituitary hypertrophy. Cerebrospinal fluid analysis revealed an aseptic lymphocytic meningitis. Pituitary biopsy confirmed the diagnosis of LH. The patient was started on prednisone 70 mg per day. She improved clinically and radiologically and remained free of symptoms thereafter. At a recent follow up the MRI showed an empty sella turcica. Hereby we illustrate a yet unreported pattern of LH presenting as a recurrent aseptic meningitis. We also describe one of the long-term course of the disease which is still unpredictable.
