57-year-old male with ulcer dorsal to the calcaneus. Evaluate for osteomyelitis. TENDONS: Mild thickening of the peroneus brevis tendon is compatible with tendinosis. Convex bulging appearance of the distal Achilles tendon is also compatible with tendinosis. The remaining flexor and extensor tendons are within normal limits.LIGAMENTS: No significant abnormality noted.ARTICULAR SURFACES AND BONE: There is a deep ulcer in the soft tissues dorsal to the calcaneus, with erosion of the underlying calcaneal cortex measuring approximately 1.5 cm in length. Just deep to the eroded cortex there is decreased T1 and increased T2/STIR signal within the posteromedial aspect of the calcaneus, compatible with osteomyelitis. No drainable abscess is identified.ADDITIONAL
1.Deep ulcer within the posterior soft tissues of the foot with osteomyelitis of the underlying posteromedial calcaneus. No drainable abscess identified.2.Peroneus brevis and Achilles tendinosis.
