A variety of conditions can produce clinical and imaging appearances similar to articular masses. MRI is the imaging method of choice for detection and characterization of articular mass-like lesions. Although many of these lesions have nonspecific findings at MRI, careful analysis of lesion morphology and signal characteristics helps to narrow the differential diagnosis. This CME article will aid radiologists to recognize important MRI findings that help to diagnose and characterize articular mass-like lesions.
