摘　　要：目的 :评估CT扫描对体部软组织神经鞘瘤的诊断价值。方法 :在 10例患者作CT扫描时发现 11个肿瘤 ,病理证实为神经鞘瘤。结果 :本组 11个肿瘤发生在颈部 3个 ,胸膜、腋窝各 2个、枕后、腹直肌、盆壁和臀大肌各 1个。CT征象 :①边缘光滑 ,圆形、卵圆形或梭形肿块 ;②具有包膜 ;③肿块密度与肌肉组织相近 ,可有坏死液化区 ;④肿块与毗邻组织分界清楚。结论 :CT对发现体部软组织内神经鞘瘤敏感性很高 ,多数可作出定性诊断。Objective:To determine whether a schwannoma could be specified by means of CT modality.Methods:Ten patients were scanned by CT either due to a palpable symptomless mass or on routine health care examination.Eleven masses were discovered on CT and verified to be schwannoma by pathology.Results:Among those 11 masses,3 masses were located in the neck (3 cases),2 pleural (1 case),2 axillary (2 cases) and 1 in the suboccipital, buttock, abdominal rectus muscle and pelvic wall, respectively. The main CT signs of schwannoma in this series were:①round, ovale or fusiform shaped mass with sharply defined margin;②capsule formation;③homogenous near muscle density with or without liquefication of the mass and ④the tumoral masses were usually separated with neighbourhood structures.Conclusion:CT is a sensitive tool in detection of a schwannoma in the soft tissue of the body,and in majority of these masses could be specified preoperatively.
