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.
CONCLUSION
Pelvic eosinophilic granuloma has characteristic imaging features, and combination of the imaging findings can improve the diagnosing accuracy.
目的
探讨骨盆嗜酸性肉芽肿的影像学诊断方法，提高诊断准确率。
方法
对24例经病理证实的嗜酸性肉芽肿患者的平片、CT及MRI资料进行回顾性分析。所有患者均行X线检查，17例行CT扫描，9例行MRI检查。
结果
24例嗜酸性肉芽肿中，6例病变位于耻骨，5例位于坐骨，13例位于髂骨。病变表现为骨质破坏或不规则骨质破坏，伴有骨膜反应及软组织肿块。
结论
骨盆嗜酸性肉芽肿具有特征性影像学表现，综合影像学表现可提高诊断准确率。
