Abstract:
Objective To analyze and summarize the MRI findings and clinical features of focal periphyseal edema(FOPE)in adolescents.Methods A retrospective analysis was conducted on the MRI and clinical data from 25 patients(29 knee joints)diagnosed with FOPE.All patients had no history of trauma.The MRI imaging features were analyzed by two senior musculoskeletal radiologists,and the diagnostic value and clinical significance of MRI were summarized.Results In 25 patients,34 lesions were found in 29 knee joints,including 20 in the femoral periphyseal plate region and 14 in the tibial periphyseal plate region.30 lesions were located in the central 2/3 area of the periphyseal plate and 4 were located in the peripheral 1/3 area of the periphyseal plate.On MRI,the lesions appeared as patchy areas of low signal on T1WI and high signal on fat suppression proton density weighted imaging(PDWI),extending from the periphyseal plate to the epiphysis and metaphyseal side with ill-defined borders.The longitudinal diameter of the lesions ranged from 0.4-1.7 cm,and the transverse diameter ranged from 0.3-1.7 cm.Apart from the FOPE,no other abnormal positive findings were observed on MRI of the knee joints in all patients.Conclusion FOPE in adolescents exhibits characteristic MRI findings,which may be related to closure of the periphyseal plate and knee joint pain in adolescents.
