  • Figure 1.
    Figure 1.

    Initial magnetic resonance imaging examination with (A) coronal T1, (B) coronal short T1 inversion recovery (STIR), and (C) axial T2 fat saturation sequences. View A shows no evidence of osseous erosions or marrow-replacing process to suggest osteomyelitis. Views B and C show fluid within the carpal tunnel and associated innumerable low T2 foci, presumed rice bodies (white arrows).

    Figure 2.

    Most recent magnetic resonance imaging examination at the carpal level with (A) coronal T1 and (B) coronal postcontrast T1 fat saturation sequences with inclusion of the metacarpals on (C) coronal T1, (D) coronal short T1 inversion recovery (STIR), and (E) coronal post-contrast T1 fat saturation sequences. Views A and B show joint space narrowing, osseous erosions (asterisks), and synovial enhancement (asterisks) throughout the carpals. Dashed white arrows show marrow edema (views C and D) and enhancement (view E) of the second metacarpal concerning for osseous involvement of the adjacent infectious process within the carpals. Additionally, complex enhancing fluid is seen at the distal radioulnar joint (solid arrows in views D and E).
