Pain MENISCI: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: There is a 2.2 cm TV x 1.7 cm AP x 1.9 cm CC lesion at the posteromedial aspect of the distal femoral metaphysis demonstrating heterogeneously high signal on T1 and T2 sequences. There mild elevation of the adjacent cortex. No associated soft tissue mass or surrounding inflammation is evident.No significant cartilaginous abnormality noted.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Cortically based lesion in the posterior medial distal femur. The appearance of this lesion is non-specific though suggestive of a benign cortical desmoid. Given the patient's age and pain, repeat imaging of this lesion to assess for potential change would increase specificity for an aggressive etiology such as neoplasm or infection.Additionally, if prior imaging is available and can be submitted, comparison can be made and an addendum to this report issued.
