A 55-year-old woman first noticed palpable nodules in the left lower extremity. Two months later, she noticed another nodule on the other side and visited our hospital.
On physical examination, she had scatterd intramuscular nodules without pain or muscle atrophy.
MR imaging showed multiple nodules in the involved muscles. These structures were typical "stripe sign" with high signal on T1 and T2 weighted images at the peripheral portion, and low signal on all the sequence at the central structure. High uptake nodules were detected on Galium scintigraphy. Chest X ray did not show features of bilateral lymphadenopathy (BHL). Biopsy spicement of the palpable intramuscular nodule showed glanulomas composed of epitheliod cells without caseous necrosis. This was diagnosed as nodular muscular sarcoidosis. This case proved that MR imaging is very helpful for diagnosing muscular sarcoidosis from the pathological features of the nodules.
