title: A case of nodular-type muscular sarcoidosis: findings of imaging, histopathology, and polymerase chain reaction.
abstract: We report a case of nodular-type muscular sarcoidosis with no systemic symptoms. Thallium-201 scintigraphy showed intense uptake in the muscular lesion mimicking malignant soft tissue tumor. Magnetic resonance imaging (MRI) demonstrated characteristic signal patterns of peripheral high intensity with central low intensity ("three stripes" pattern). Microscopy revealed sarcoid granuloma with typical histopathological characteristics. Propionibacterium acnes was detected on polymerase chain reaction analysis of the excised tissue.
