Case report: Isolated pituitary sarcoidosis: MRI findings

Abstract

Sarcoidosis is a multisystem granulomatous disease with an unknown etiology. Symptomatic central nervous system involvement occurs in 5% of cases. MRI shows a wide range of central nervous abnormalities including hypothalamic-pituitary infiltrating lesions, cerebral parenchymal masses, leptomeningeal lesions, and focal white-matter lesions. The patients with sarcoidosis may rarely present with sellar masses. A case of isolated pituitary sarcoidosis was presented in this report with pretreatment and post-treatment MRI pictures.
