摘　　要：目的：为提高颅骨嗜酸性肉芽肿的放射学诊断水平并识别其演变过程。材料和方法：回顾性分析４２例经手术及活检病理证实的颅骨嗜酸性肉芽肿的Ｘ线和ＣＴ表现，并随访观察３０例病变的演变过程。结果：本文描述了病变的Ｘ线和ＣＴ的各种表现。按照病变演变过程将病变分成４期：１早期：病变局限于板障内。２进展期：病变破坏颅板并累及邻近软组织。３痊愈期：软组织肿胀或肿块消除，往往留下边缘清楚或光整的颅骨缺损。４修复期：颅骨破坏先内板后外板向心性地直接骨化修复。结论：Ｘ线平片及切线位片仍然是诊断和随访颅骨嗜酸性肉芽肿的首选和主要的检查方法，ＣＴ可作为补充检查。ＣＴ显示颅骨破坏边缘，病变内的残留小骨，脂质及软组织肿块层次优于Ｘ线检查。Abstract:PURPOSE:TO improve radiologic deagnostic accuracy of eosinophilic granuloma of the skull and identify its evolution MATERIALS and METHOSE:The authors retrospectively studied X-ray and CT findings of eosinophilic granuloma of the skull of 42 cases pathologically proved and followed up to study evolutions of 30 cases with eosinophilic granuloma of the skull ofr 8-26 menths.RESVLT:Varieties of radiologic findings of eosinophilic granuloma of the skull were described in detail.According to radiologic findings of evolution of lesion which were divided into 4 stages:(1)Early stage:Lesion local -ized in diploe of skull.(2)Advanced stage:Lesion destructed the skull table and extended into adjacent soft tissues.(3)Cured stage:A soft tissue swelling or mass was subsided and radiologic findings of the skull tends to show a destructive bone of having clear or sharp border was remained.(4)Repaired stage:Recovery of the destructive skull usually began with destructive area of the inner table followed by destructive area of the outer table in a centripetal way of directed osteogenesis.In addition.radiologic diagnosis and differentiation of eosinophilic granuloma of the skull were discussed.CONCLUSION:Plain film and tangential film were still the method of initial choice and main examination in diagnosis and follow up of eosinophilic granuloma of the skull.CT could be used as a supplement for X-ray diagnosis.CT was better than X-ray examination in demostrating the edge appearance of bone destruction,residual bonelet and lipid within lesion and soft-tissue mass.
