Figure 2. MRI scans of the left lower foot. (A) Contrast-enhanced T1-weighted fat saturation MRI in the coronal plane of the foot shows marked contrast enhancement of the distal fifth metatarsal bone and proximal phalanx with signs of early destruction of the articular surfaces of the metatarso-phalangeal joint space (white arrow). There was also prominent contrast enhancement of the plantar and dorsal muscles of the foot extending from the fifth to the second toe suggestive of extensive myositis. (B) Contrast-enhanced T1-weighted fat saturation MRI in the axial plane of the foot. The axial image showed a sinus tract extending to a subcutaneous abscess adjacent to the base of the fifth metatarsal bone, with an overlying skin ulcer (asterisk). MRI – magnetic resonance imaging.
