Multiple rice body formation is an uncommon disorder which resembles synovial chondromatosis both radiologically and clinically. The clinical symptoms are usually non-specific. We report on a pathologically proven multiple rice body formation in both the left subacromial-subdeltoid bursa and knee joint in a 4-year-old girl.
OBJECTIVE: Our aim was to describe the MRI characteristics of septic and nonseptic olecranon bursitis. MATERIALS AND METHODS: MRI contrast-enhanced examinations (n = 19) of 35 patients with olecranon bursitis (septic, n = 14; nonseptic, n = 21) were jointly reviewed by two musculoskeletal radiologists. We evaluated bursa size, extent of marginal lobulation, septation, concomitant elbow joint effusion, soft-tissue edema, rim enhancement, soft-tissue enhancement, degree of fluid complexity, definition of bursa margins, presence of edema, thickening of the triceps tendon, and bone marrow edema. RESULTS: Comparison of septic and nonseptic bursitis yielded the following results: marginal lobulation, 79% (11/14) versus 48% (10/21), p = 0.14; bursa septation, 64% (9/14) versus 57% (12/21), p = 1.0; moderate or marked complexity of bursa fluid, 64% (9/14) versus 29% (6/21), p = 0.15; poorly defined margins, 64% (9/14) versus 67% (14/21), p = 1.0; elbow joint effusion, 86% (12/14) versus 52% (11/21), p = 0.12; moderate to marked soft-tissue edema, 64% (9/14) versus 33% (7/21), p = 0.1; edema of the triceps, 57% (8/14) versus 48% (10/21), p = 0.73; thickening of the triceps, 43% (6/14) versus 14% (3/21), p = 0.21; bone marrow edema, 29% (4/14) versus 5% (1/21), p = 0.13; rim enhancement, 100% (11/11) versus 75% (6/8), p = 0.31; soft-tissue enhancement, 100% (11/11) versus 63% (5/8), p = 0.1. CONCLUSION: Septic and nonseptic olecranon bursitis present with a considerable overlap of MRI findings without statistically significant differences. Septic olecranon bursitis can be excluded in the absence of bursal and soft-tissue enhancement.
An adhesion of the subacromial bursa in the shoulder causes pain during joint motion and restricts the range of motion of the glenohumeral joint. To understand the biologic features of an adhesion, the gene expressions in adhesive subacromial bursa were analyzed by quantitative real-time reverse transcriptase-polymerase chain reaction. The gene expressions in adhesive subacromial bursae were approximately threefold to fourfold greater than those in nonadhesive bursae for the genes for Type I and Type III procollagens, CD34 antigen in vascular endothelium, hyaluronan synthase-3, and interferon-gamma. The gene expression of interleukin-8 was predominant in adhesive bursa. The gene expressions of hyaluronan synthase-1, hyaluronan synthase-2, and interleukin-10 which is an antiadhesive cytokine were predominant in nonadhesive bursae. Chromatography analysis revealed that a hyaluronan, of which molecular weight was more than 100 kDa, was present in the cavity of nonadhesive subacromial bursae. It is suggested that pathologic fibrosis and vascularization are maintained by the presence of interferon-gamma and interleukin-8 in adhesive subacromial bursae and that high molecular weight hyaluronan or interleukin-10 plays a role for antiadhesion.
