(a-c) AP, lateral, and oblique MRI of the right elbow with a subtle area of lucency (arrows) in the metaphysis. (d) Axial T1 postcontrast MRI with an enhancing lesion (large arrow) in the bone with anterior cortical disruption and enhancement anterior to the humerus extending to the lateral sinus tract (small arrow).

(a, b) AP and lateral x-rays showing a distal humeral lucency concerning for chronic osteomyelitis. (c, d) Axial T1 post contrast MRI. (c) The large arrow denotes nidus of infection. (d) The large arrow denotes anterior cortical disruption. The small arrows denote purulent fluid collection in elbow joint. (e) and (f) are radiographs one year after irrigation and debridement.

X-rays showed a lucency over the distal humerus (Figures 2(a) and 2(b)), suspected to be a nidus for chronic osteomyelitis. MRI demonstrated an effusion and humeral changes (Figures 2(c) and 2(d)) consistent with osteomyelitis and septic arthritis.
