Extensive tarsal abnormality centred in the intermediate cuneiform, demonstrating bony destruction of the cuneiform as well as base and body of the second metatarsal, consistent with septic arthritis and osteomyelitis. Marrow signal changes in the adjacent medial and lateral cuneiforms as well as the 3rd metatarsal base are present, potentially reactive or early osteomyelitis.
There is a 2 cm collection at the plantar aspect of the 2nd tarsometatarsal, which appears extending from the joint space with further peripherally enhancing multiloculated foci at the dorsolateral aspect of midfoot, with surrounding enhancing soft tissue, which also could represent a second collection in continuity with the infected joint.
The ankle joint and hindfoot are normal.
Conclusion:
Intermediate cuneiform and second metatarsal septic/ arthritis and established osteomyelitis with either reactive or early osteomyelitic changes in surrounding bones.
Associated soft tissue abscesses.
