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

Figure 5

A 13-year-3-month-old female with FOPE zones at both proximal tibiae. Findings: (a) sagittal proton density fat-saturated image of the left knee shows 13 mm in diameter area of periphyseal edema at the metaphyseal side of the proximal tibia physis (arrow). The proximal tibia physis is narrowed but remains open. (b) Coronal proton density fat-saturated image shows the periphyseal edema to be on both sides of the proximal tibia physis. The coronal image better demonstrates the periphyseal edema involvement of both the epiphyseal and metaphyseal sides of the physis (arrow). Technique: (a) sagittal PD fat-saturated MRI (TR = 2,959.1, TE = 30), ST = 3 mm, spacing = 3.3 mm, FOV = 14 cm, and matrix = 364 × 261; (b) coronal PD fat-saturated MRI (TR = 2,504.2, TE = 30), ST = 2.5 mm, spacing = 3.3 mm, FOV = 15 cm, and matrix = 312 × 244.
