肩胛部弹力纤维瘤螺旋CT诊断(附5例报告)

Spiral CT diagnosis of elastofibroma scapulace(5 case reports attached)

目的探讨肩胛部弹力纤维瘤的CT表现。方法回顾性分析经手术证实的5例肩胛部弹力纤维瘤的CT表现及其特点,所有病例均行CT平扫及多平面重组,5例行静脉增强检查。结果平扫显示肩胛下角内侧前锯肌、背阔肌及菱形肌深层与胸筋膜间不规则实性肿物。双侧12例,肿物呈扁丘形,基底在胸筋膜侧,肿物弧形压迫相邻肌肉,周围脂肪间隙清晰。肿物其密度不均匀,呈肌肉密度与脂肪密度间隔排列。5例行CT静脉增强扫描,肿物轻度强化,与肌肉强化程度相似。结论螺旋CT是诊断肩胛部弹力纤维瘤的有效方法。

Objective To study CT manifestations of elastofibroma scapulace.Methods CT findings of 5 patients with surgically proved elastofibroma scapulace were retrospectively analyzed. All cases underwent CT plain scans of the chest and multiple-planum reconstruction and 5 cases underwent contrast-enhance CT scans preoperatively.Results There were scapulace irregular masses in 15 cases and all masses occurred between latissimus dorsi and thoraco-fascia. 12 cases had double lesions. The masses were shaped as half oval and the bottom was on thoraco-fascia. The nearby muscle was oppressed by lesions. The tumors had definite margins surrounded by fat.Unhomogeneous density occurred in all cases. The muscle and fat were intervally arranged. After contrast enhancement,light enhancement was seen in 5 cases and the enhancement degree was similar to the muscle＇s.Conclusion CT is an effective modality in diagnosing the elastofibroma scapulace.
