摘要
目的分析颅盖部骨瘤的X线、CT表现,讨论本病的CT诊断价值。方法18例经手术病理证实的颅骨骨瘤患者均行CT扫描和摄X线平片。结果18例骨瘤共有21个病灶,发生自颅骨内板或外板。病变呈丘状或分叶状凸起,其中小丘状病灶18个,分叶状病灶3个,多发病例3个。骨瘤边缘光滑,基底较宽,骨瘤与颅骨内、外板相连。2例发生于颅骨内板分叶状骨瘤引起局部脑组织受压。根据骨瘤的密度可将其分为三型:①致密骨型;②松质骨型;③混合型。结论CT可以明确诊断颅盖部骨瘤,特别是对于发生于颅骨内板的骨瘤,能发现X线不能显示的征象,具有较高的诊断价值。
Objective To analyze the X-ray and CT features of cranial vault osteomas and discuss the CT diagnosis value. Methods CT scanning were performed in 18 cases of clinically and pathologically proved cranial osteomas, all patients underwent X-ray film. The clinical and imaging features were analyzed and compared with the pathological findings. Results Twenty-one osteomas were observed in these 18 cases,which arising from the inner/outer tableof calvarium, including showing enostotic convexity in 18 osteomas and lobulated in 3 osteomas. Multiple osteomas were observed in 3 cases. The margins of eachosteoma were smooth or smoothly lobulated. The base of the osteomas was wide and attached to the underlying bone. The local cerebrum were pressed by 2 lobulated osteomas which arising from the innertable of calvarium. According to the dense of the osteomas, it could be classification ①Compact or ＇ ivory＇ osteomas, ②Trabecular osteomas, ③ mixed pattern. Conclusion The diagnosis of typical cranial osteomas can be made with CT, especial the osteomas that arising from the inner table of calvarium, CT can find more indication than X-ray and can help make differential diagnosis.
