【摘要】目的 探讨骨嗜酸性肉芽肿的CT和MRI表现及其病理学基础.方法 回顾分析18例骨嗜酸性肉芽肿的CT、MRI表现和病理资料.结果 颅骨6例,长骨4例,脊柱4例,骨盆3例,下颌骨1例.CT及MRI所见具有类似肿瘤的特征,表现为溶骨性骨质破坏,边缘清晰或稍模糊,其中无反应性骨硬化者12例,有反应性骨硬化6例,病理上分别处于肉芽肿期及退缩期.病灶无膨胀到轻中度膨胀,部分病例可见骨膜增生及软组织肿块.病变在病理学上具有类似炎症的特征,表现为局限性肉芽肿形成,郎格罕组织细胞和多种炎症细胞浸润.结论 嗜酸性肉芽肿影像学表现与病理学分期有相一致的对应关系,由于病变同时具有肿瘤和炎症的特征,故影像学表现具有多样性和易变性,易导致误诊.%Objective To investigate the CT and MRI manifestations and its pathological basis of cosinophilic granuloma of bone.Methods CT, MRI and pathologic data in 18 cases with eosinophilic granuloma of bone were retrospectively analyzed. Results In 18 patients, the lesions located in skull in 6, long bone in 4 , vertebrae in 4, pelvis in 3 and mandible in 1. CT and MRI findings presented a tumor-like characteristics, including osteolytic bone destruction with definite or slightly blurred margins, there were reactive osteo-sclerosis in 6 cases and no reactive osteo-sclerosis in 12 cases, which were at granulomatous and degeneration periods at pathology.
