63-year-old male with infected stump. Evaluate for osteomyelitis. RIGHT FOOT:Postsurgical changes of prior amputation through the first through fifth metatarsals. There is no bone marrow signal abnormality to suggest osteomyelitis of the right foot, as clinically questioned. No sinus tract or cortical destruction are identified. There is decreased signal abnormality in within the remnant of the 5th metatarsal which appears to correspond to sclerosis seen on recent radiographs. There is increased signal abnormality within the soft tissues along the plantar aspect of the calcaneus and proximal midfoot. There is also increase in signal abnormality within the flexor digitorum and flexor hallucis longus muscle bellies. No focal fluid collection is identified to suggest abscess formation.LEFT FOOT:The patient is status post transmetatarsal amputation through the first and fifth metatarsals. There is increased T2 and decreased T1 signal abnormality within the remnant of the fifth metatarsal base, suspicious for osteomyelitis. No sinus tract or cortical destruction are identified. There is increased signal abnormality within the soft tissues in the surrounding area. Additionally there is decreased T1 and T2 signal abnormality within the distal portions of the fourth and fifth metatarsal remnants which appears to correspond to sclerosis seen on recent foot radiographs. No focal fluid collection is identified to suggest abscess formation.
1. Findings suspicious for osteomyelitis of the 5th metatarsal remnant of the left foot, as described above.2. Findings suggestive of soft tissue inflammation/edema without evidence of osteomyelitis of the right foot.
