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

Figure 8

A 14-year-2-month-old female with FOPE zone of the proximal tibia. Findings: (a) sagittal proton density image shows 14 mm in diameter area of periphyseal edema involving both sides of the proximal tibia physis (arrow). Edema is greater along the epiphyseal side of the physis. (b) Axial proton density image at the level of the proximal tibia physis shows the area of periphyseal edema within the anteromedial aspect of the central proximal tibia (asterisk). Technique: (a) sagittal PD fat-saturated MRI (TR = 2,922.8, TE = 30), ST = 3 mm, spacing = 3.3 mm, FOV = 14 cm, and matrix = 364 × 261; (b) axial PD fat-saturated MRI (TR = 2,803.1, TE = 30), ST = 3 mm, spacing = 3.3 mm, FOV = 15 cm, matrix = 376 × 297.
