Sarcoidosis is a granulomatous disease of unknown etiology. It commonly involves the pulmonary hilar lymph nodes, lungs, eyes, liver, and skin; however, skeletal muscles are rarely involved. We experienced a case of recurrent muscular sarcoidosis of the bilateral surae. The patient was a 57-year-old female, who presented masses with pain in her bilateral surae. Serological examination was within the normal range. MRI of the nodule showed a star-shaped area of lower signal intensity surrounded by an area of higher signal intensity. Marked uptake of 67 Ga was observed in these regions. Resection was performed on the right surae. Histological examinations showed granulomas composed of multinuclear giant cells and epithelioid cells. Sarcoidosis was diagnosed. Four months later, symptoms disappeared and the size of higher signal intensity area of the nodule reduced. MRI and 67 Ga scintigram were useful for diagnosis, and resection was successful in this patient.
