Bicipital radial bursitis: CT and MR appearance

The authors present two cases of bicipital radial bursitis in the elbow. In these two cases, different CT and MR imaging patterns were observed. In th e first case, postcontrast CT inhomogeneously enhanced the entire lesion. T I-weighted MR images showed the lesion with iso-signal intensity with muscl e. T2-weighted images demonstrated the lesion with inhomogeneous high signa l intensity, with internal, linear hypointensity. Histologically, the lesio n consisted of hypertrophic synovia. In the second case, postcontrast CT fa iled to enhance the lesion. T2-weighted MR images showed the lesion with ho mogeneous, marked high signal intensity. Histologically, the lesion consist ed of a monocystic bursa lined by thin synovial lining layers. (C) 2001 Els evier Science Ltd. All rights reserved.
