[Idiopathic granulomatous hypophysitis: clinical apppearance and imaging].
Idiopathic granulomatous hypophysitis is a chronic inflammation of the pituitary gland. It is a rare occurrence and is diagnosed only on pathologic examination. We report a case of a 23-year-old female patient presenting with polyuria and polydipsia associated with a pituitary failure and hyperprolactinemia. MRI study showed a space occupying lesion of the pituitary gland with a marked enhancement after gadolinium injection. Pituitary biopsy was consistent with the diagnosis of idiopathic granulomatous hypophysitis. The aim of this work is to discuss the different clinical and radiological aspects of the disease with a special emphasis on differential diagnosis.
