Case Report
Unusual Presentations of Focal Periphyseal Edema Zones: A Report of Bilateral Symmetric Presentation and Partial Physeal Closure
Table 1
FOPE zone clinical summary.
| Etiology | Unknown. Likely due to mechanical stress placed on the physis during early physeal closure. |
| Incidence | Rare. Only a small case series reported in the literature. |
| Gender ratio | Unknown. There may be a higher incidence in females. |
| Age of predilection | 12–16 years old. |
| Risk factors | No known risk factors. |
| Treatment | No treatment for asymptomatic lesions. Symptomatic lesions treated conservatively with protected weight bearing. |
| Prognosis | Excellent. Self-limited process that likely resolves shortly after physeal closure. |
| Imaging findings | Focal enhancing bone marrow edema on both sides of a central portion of a narrowed or partially closed physis. |
