Chronic ulceration. Question of osteomyelitis. There is complete destruction of the third metatarsal head with abnormal low T1, high T2 signal, and enhancement extending to the base compatible with osteomyelitis. Additionally, there is destruction of the third digit proximal phalanx. Abnormal signal within the third digit middle phalanx is compatible with osteomyelitis. There is low T1 signal along the lateral aspect of the second metatarsophalangeal joint, however, no definitive T2 signal abnormality or enhancement. Bone marrow signal within the remaining bones appears within normal limits. There is a 1.5 cm collection in the location of the third metatarsal head with peripheral enhancement and central low signal compatible with an abscess. An enhancing tract is seen communicating from the plantar skin surface to this collection.
Osteomyelitis with abscess formation as described above.
