ABSTRACT
OBJECTIVE: Sarcoidosis is a granulomatous multisystem disorder that may uncommonly involve muscle. We report the sonographic and MRI findings in three cases of the nodular type of muscular sarcoidosis. CONCLUSION: Intramuscular hypoechoic well-defined nodules in young patients or patients with a history of sarcoidosis suggest the diagnosis of intramuscular sarcoid. MRI is useful in detecting muscle sarcoid, evaluating the extent and distribution of muscle involvement, and monitoring the patient during follow-up after steroid therapy. MRI showed nodules that were iso- or hyperintense relative to muscle on T1-weighted sequences. On T2-weighted images and STIR sequences, we observed numerous intramuscular nodules of homogeneous high signal intensity. All nodules enhanced homogeneously on contrast-enhanced T1-weighted sequences. Disappearance of all nodules was seen on follow-up sonograms and MR images after patients had received steroid therapy.

Bilateral facet dislocation of the lumbosacral joint is an uncommon injury. We report on the imaging findings in a patient who had an acute disc herniation associated with a bilateral traumatic lumbosacral dislocation.

Osteoarticular manifestations of SAPHO syndrome include vertebral lesions, typically in the thoracic segment. Chronic inflammatory changes are well depicted by MRI. We report the imaging findings with a 10-year follow-up in a case of SAPHO syndrome with marked cervical lesions.
