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

Beckmann N, Spence S - Case Rep Radiol (2015)

Bottom Line: Since the original case series describing these areas of periphyseal edema, there has been little published in regard to FOPE zone outside of review articles.We present a set of three patients identified with focal periphyseal edema zones around the knee and compare our findings with the initial case series.We include a patient presenting with bilateral, nearly symmetric, focal periphyseal edema zones of the proximal tibia physis and a patient with partial closure of the physis at time of presentation, which were not reported in the original case series.

ABSTRACT
Focal periphyseal edema (FOPE) zones are areas of periphyseal edema seen near the time of physeal closure which are believed to be a physiologic phenomenon related to changes in distribution of forces around the physis as it closes. Since the original case series describing these areas of periphyseal edema, there has been little published in regard to FOPE zone outside of review articles. We present a set of three patients identified with focal periphyseal edema zones around the knee and compare our findings with the initial case series. We include a patient presenting with bilateral, nearly symmetric, focal periphyseal edema zones of the proximal tibia physis and a patient with partial closure of the physis at time of presentation, which were not reported in the original case series.

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.

Mentions: Presenting radiographs of the right knee were normal (Figure 10). MRI of the right knee showed pivot-shift bone marrow contusion pattern in the lateral compartment and root ligament avulsion of the lateral meniscus posterior horn (Figure 11). A 5 mm FOPE zone was also present in the central portion of the distal femur physis (Figure 12). The distal femur physis was still open.
