9-year-old male status post treatment of possible osteomyelitis of right calcaneus, continued pain TENDONS: The extensor and flexor tendons are intact.LIGAMENTS: The medial and lateral collateral ligaments are intactARTICULAR SURFACES AND BONE: Interval improvement in marrow edema within the calcaneus with a residual well defined focus of increased T2 and decreased decreased T1 signal along the inferior margin of the calcaneus adjacent to the inferior aspect of the apophyseal physis, measuring 6 mm in diameter. This focus corresponds to a lucency seen on prior CT which was also present on the CT biopsy exam and subsequent MRI. A linear tract of low T1 signal intensity within the posterior calcaneus likely represents a prior needle biopsy tract with minimal residual associated edema. The remaining bone marrow signal is normal.ADDITIONAL
Interval improvement in marrow edema of the calcaneus. Persistent well-defined focus of increased T2 and decreased T1 signal within the calcaneus is nonspecific, but was present on prior CT and MR exams as described above.
