Sarcoidosis is a multisystem noncaseating granulomatous disorder of unknown etiology that can be found in almost any organ, but symptomatic respiratory muscle involvement is rare. We herein report the case of a 77-year-old woman with diaphragm sarcoidosis diagnosed by a computed tomography (CT)-guided needle biopsy that was successfully treated with a corticosteroid. The patient presented with dyspnea that lasted for two weeks and respiratory failure. CT revealed diffuse diaphragm thickening with contrast enhancement, which might be a characteristic imaging finding for diaphragm myopathy/myositis, including sarcoidosis. A CT-guided needle biopsy proved useful for the diagnosis of diaphragm sarcoidosis.
