Figure 2 Arthroscopic features of rice bodies. (A) Arthroscopic view reveals patchy capillary networks (red arrowheads) localized to the synovial surface surrounding rice body clusters in the subacromial bursa, without vessels penetrating or encircling the lesions. (B) High-magnification inspection confirms absence of intralesional vessels in single rice bodies (0.4–1.1 cm), which exhibit smooth, translucent surfaces without vascular penetration or superficial telangiectasia.
