长骨嗜酸性肉芽肿的影像诊断

Diagnostic imaging of eosinophilic granuloma of long bones

目的 探讨长骨嗜酸性肉芽肿的影像学特征.方法 回顾性分析经病理证实长骨嗜酸性肉芽肿患者的影像学资料.结果 16例患者共检查出病灶21处,其中股骨有12处病灶,胫骨5处,腓骨2处,桡骨2处.影像学表现主要为骨质破坏、皮质改变、骨膜反应、软组织肿块.结论 长骨嗜酸性肉芽肿的影像学表现具有一定的特征性,结合X线平片和CT、MRI,可提高对该病的影像学诊断能力.

Objective To explore the radiologic features of eosinophilic granuloma of long bones. Methods The radiologic data of 16 patients with eosinophilic granuloma confirmed by pathology were analyzed. Results 21 lesions were examined in the 16 patients, including 12 lesions in femur, 5 in tibia, 2 in fibula, and 2 in radius. The main imaging findings included bone destruction, cortex alteration, periosteal reaction, and soft tissue mass. Conclusions Eosinophilic granuloma of long bones presents special features on radiologic imaging. The combination of X-ray, CT, and MRI could help enhance the accuracy of diagnosis.
