摘要
目的探讨头皮软组织肿块的CT表现及其诊断价值。方法93例头皮软组织肿块,经手术病理证实41例,活检13例,临床随访确诊39例;其中男性68例,女性31例;平均年龄36.6岁。全部病例均行CT横断位平扫,18例增强扫描;骨窗及脑窗摄片。结果将头皮软组织肿块的CT表现归纳为含脂肪密度未累及颅骨、软组织密度未累及颅骨、软组织密度累及颅骨三类,93例正确诊断76.34%,良性诊断特异性74.24%(49/66例);恶性诊断特异性81.48%(22/27例)。结论CT因能明确显示头皮肿块位置、大小、形态、密度及与颅骨、颅内的关系等,是临床不可或缺的重要手段。
Objective To dicuss CT findings and the diagnostic value of the soft-tissue masses in the skin of scalp. Methods 93 patients(63 men and 31 women,average aged 36.6 years)with soft-tissue mass in the skin of scalp proved by surgical pathology(n=41),bioscopy(n=13) or clinic information(n=39) were analyzed. Axial CT plain scan was performed in all cases,and enhanced CT in 18 cases. Result The lesions were classified as 3 patterns based on CT appearances:mass contained fat density with normal cranial bone;parenchymal mass without cranial bone destruction and parenchymal mass with cranial bone destruction. The overall accuracy of CT in the diagnosis was 76.34%and the specificity for the benign and malignant lesions were 74.24%(49/66) and 81.48%(22/27),respectively. Conclusion CT is a clinical necessary and important means for clearly demonstrating the location、size、shape、density of the scalp's mass and its relationship with the cranial bone and cranial cavity.
