[Imaging diagnosis of pelvic eosinophilic granuloma and analyses of the misdiagnoses].
OBJECTIVE
To explore the imaging diagnosis of pelvic eosinophilic granuloma and improve diagnosis accuracy.


METHODS
A retrospective analysis of the plain film, CT and MRI was conducted in 24 cases of pathologically confirmed eosinophilic granuloma. All the patients received radiography, CT scan was performed in 17 cases and MRI was done 9 cases.


RESULTS
In the 24 cases of eosinophilic granuloma, 6 lesions were located in the pubis, 5 in the ischium and 13 in the iliac region. The lesion showed bony destruction or irregular bony destruction, with periosteal reaction and soft tissue mass.


CONCLUSIONS
Pelvic eosinophilic granuloma has characteristic imaging features, and combination of the imaging findings can improve the diagnosing accuracy.
