Pain and swelling Osseous structures: There are destructive and erosive changes of the midfoot, tibiotalar joint, and talocalcaneal joint reflective of Charcot arthropathy. There is no definite marrow abnormality to confirm osteomyelitis. Metallic susceptibility artifact is noted in the medial aspect of the calcaneus which may reflect prior surgical intervention. There is a small anterior joint effusion which contains a probable loose body.Soft tissues: There is diffuse subcutaneous edema although no discrete fluid collection is identified. There is increased signal throughout the muscles of the foot, but particularly within the plantar muscles.
1. No definite evidence of osteomyelitis or focal abscess.2. Destructive changes of the foot described above likely relate to Charcot arthropathy given the patient's history.3. Increased signal throughout the muscles of the foot may reflect diabetic myopathy.
