Unusual Presentations of Focal Periphyseal Edema Zones: A Report of Bilateral Symmetric Presentation and Partial Physeal Closure

Figure 12

A 13-year-10-month-old female with FOPE zone of the distal right femur. Findings: (a) coronal proton density fat-saturated image shows a 5 mm area of periphyseal edema slightly eccentrically located on both sides of the distal femur physis (arrow). The edema is slightly more prominent on the epiphyseal side of the physis. (b) Sagittal proton density fat-saturated image again shows the eccentrically located area of periphyseal edema in the distal femur physis (arrow) with the edema again slightly more prominent on the epiphyseal side. The distal femur physis is narrowed but remains open. Technique: (a) coronal PD fat-saturated MRI (TR = 2,826.1, TE = 30), ST = 2.5 mm, spacing = 3.3 mm, FOV = 15 cm, and matrix = 312 × 244; (b) coronal PD fat-saturated MRI (TR = 2,826.1, TE = 30), ST = 2.5 mm, spacing = 3.3 mm, FOV = 15 cm, and matrix = 312 × 244.
