The nodule in the muscle of a patient with muscular sarcoidosis was examined by US, CT, MRI, ⁶⁷Ga scintigraphy, and five characteristics of the images were noted: There were (1) long nodules along muscle fibers, (2) a bright star in the short axial sonograms, (3) a dark star in the axial MR images, (4) three stripes in the long axial sonograms and coronal MR images, and (5) long lesions with increased radionuclide uptake in the ⁶⁷Ga scintigram. Because of its relatively specific findings, ultrasound is the method of first choice for examining patients with muscular sarcoidosis of the nodular type.
