体表肿块的CT诊断价值

Value of CT in the diagnosis of body surface mass

目的:研究体表肿块的CT表现并探索其诊断价值。方法:对48例体表肿块作CT扫描,所有病例均经临床或手术病理证实。结果:CT诊断脂肪瘤11例,结核及感染10例,神经纤维瘤2例,表皮样囊肿2例,骨瘤4例,肌肥厚2例,血肿2例,骨纤维异常增殖1例,多形性腺瘤1例,脊柱侧弯畸形1例。恶性肿瘤12例。病理诊断符合率91.6%。结论:CT能明确判断体表肿块的解剖部位及大小,并能结合影像学特点及密度值作出定性诊断,结合临床资料可作出部分病因诊断。

Objective To study the CT image features of body surface mass and to evaluate its value in the diagnosis of body surface mass. Methods CT scanning was performed in 48 patients with body surface mass, which were involved in head and neck （n=29）, thoracic back （n=8）,abdomen（n=8）,buttock （n=3）. All were cases were proved by histopathology. Results It was diagnosed by CT for lipoma （n=11）, tuberculosis and inflammation （n =10）,neurofibroma （n=2）,cyst epidermoid （n=2）,osteoma（n=4）,thickening muscle （n=2）, hematoma （n=2）,fibrous dysplasia of bone （n=1）, pleomorphic adenoma （n=1）, scoliosis （n=1）, malignant tumor （n=12）.In contrast to hisopathology,accurate rate of CT diagnosis was 91.6%. Conclusion The anatomic location and side of body surface mass can be accurately defined, and characteristic diagnosis be made according to imaging features and CT density value of the mass ,moreover the partial cause could be identified in combination with clinical materials.
