摘要
目的 :探讨颅骨嗜酸性肉芽肿的影像表现及鉴别诊断。材料和方法 :回顾性分析 2 6例经病理证实的颅骨嗜酸性肉芽肿的X线、CT、MRI表现。结果 :2 6例共发现 2 9个病灶。其中单发 2 4例 (额骨 12例、顶骨 8例、颞骨 3例、枕骨 1例 ) ,多发 2例。主要表现为起源于颅骨板障并侵犯内外板、边界清楚的骨破坏 ,病灶内残留的小骨片 (钮扣骨 )、脂质和软组织肿块。CT呈不均匀密度 ,MRI呈稍长T1和稍长T2信号。结论 :X线平片是诊断基础 ,结合CT、MRI能够提高诊断与鉴别诊断水平。
Purpose: To explore Imaging diagnosis and differential diagnosis of eosinophilic granuloma in the skull. Materials and Methods: The author retrospectively studied X-ray、CT and MRI manifestations of eosinophilic granuloma in the skull of 26 cases proved by histopathology. Results: Twenty-nine lesions in 26 cases were found. They were solitary lesion in 24 cases including 11 cases in frontal bone,8 cases in parietal bone ,3 cases in occipital bone and 2 cases in temporal bone and multiple lesions in 2 cases. The lesions were demonstrated well defined osteolytic area in the skull involving the inner and outer tables with origin in the diplo, with some residual button bone and lipid within the lesion and soft-tissue mass,that had inhomogeneous density on CT,and slightly hypointensity on T1WI,hyperintensity on T2WI. Conclusion: X-ray film is a baisc method diagnosing of eosinophilic granuloma of the skull,but CT and MRI may improve diagnosis and differential diagnostic accuracy.
