摘　　要：目的探讨头皮软组织病变的CT和MRI表现,提高对此类疾病的认识。方法收集经手术病理证实的31例头皮软组织病变,其中CT检查17例,MRI检查14例。观察头皮软组织病变的部位、大小、病变边缘情况、密度或信号特征、强化幅度、有无颅骨或脑内侵犯。结果发病部位:枕部11例,顶部8例;形态:梭形20例,扁平形(5例);大小平均1.6cm×3.8cm;病变9例呈囊状表现,22例呈软组织密度或信号;3例无强化,10例有强化;2例侵犯临近颅骨,其中1例同时侵犯小脑。结论影像学能显示头皮病变位置、大小、形态、囊实性及与颅骨、颅内的关系等,是临床重要的检查方法。Objective To evaluate the clinical application of CT and MRI imaging so as to diagnose the lesions in the scalp. Methods CT （n=17） and MRI （n=14） apprearance of lesions in scalp of 31 cases were analyzed retrospectively. All the cases were confirmed by operation and pathology. The imaging characteristic analysis included the location, size, border of the lesion, density or signal, degree of enhancement and cranial bone and/or brain infiltration. Results The lesions were frequently demonstrated in occiput （n=11） and cupula （n： 8）. The lesions were frequently fusiform （n= 20） and flat in shape （n=5）. The mean size was 1.6 cruX3.8 cm. The lesions were shown in cystic form （n=12） and soft ti- ssure density or signal （n=19）. The enhancement of lesions was present in 10 cases and absent in 3 cases. Two lesions were with cranial bone destruction, one of which was with cranial bone and brain infiltration. Conclusion CT and MR can accurately display the location, size, shape ingredient and cranial bone and brain destruction soft tissue masses of scalp, which is an important way for the diagnosis.
