Female, 42 years old. Reason: Osteo of the 2nd toe History: toe infection and pain There is abnormal bone marrow signal diffusely involving the second proximal and middle phalanges. Signal is decreased on T1-weighted images and increased on T2-weighted images, with enhancement of the bone marrow. The second distal phalanx and metatarsal have normal bone marrow signal. There is additional signal abnormality in the surrounding soft tissues. These findings are compatible with osteomyelitis.There is also abnormal signal at the head of the first metatarsal, with decreased signal on T1-weighted images and increased signal on T2-weighted images, with enhancement of the bone marrow. There is additional signal abnormality in the surrounding soft tissues. The mid and proximal first metatarsal and of the first phalanges have normal bone marrow signal. These findings are compatible with additional focus of osteomyelitis.The remainder of the bones appear normal. The visualized tendons and ligaments appear intact.
Findings compatible with osteomyelitis involving the second middle and proximal phalanges as well as the first metatarsal head.
