Presentation
Diabetic foot ulcer with extensive ulceration. To exclude osteomyelitis.
Patient Data
Mortise and subtalar joints effusion
Extensive bone marrow signal changes (T1 hypointense, T2, and PD hyperintense) involving the calcaneus compatible with osteomyelitis
A sinus tract starts from the calcaneus base into the skin on the plantar aspect medial side
Abnormal bone marrow signal isointense on T1 and hyperintense on T2/PDFS images involving the midfoot bones is suggestive of osteitis
Extensive edema and fluid signal intensity also are seen within the midfoot and hindfoot intrinsic muscles and subcutaneous tissues
Fluid signal around the ankle posteromedial tendons in the background of tenosynovitis
Talonavicular joint marginal osteophyte formation.
Case Discussion
Typical findings of calcaneus osteomyelitis in patients with a diabetic foot.
