摘要
目的分析肺部平滑肌瘤（pulmonaryleiomyoma，PL）的CT特点，以提高对PI．的认识。方法回顾性分析6例经手术和病理证实的PL的CT表现及临床特征，并复习文献。结果PL6例均为单发；肿瘤大小为3．0～8．5cm，外形均呈圆形或卵圆形，边缘极其光滑；CT平扫均为中等密度，增强后均匀中等度强化4例，不均匀强化2例；1例PI．肿块实质明显斑片状强化且内部液化坏死无强化，1例环形强化，纵隔淋巴结均未见明显增大。结论肺部平滑肌瘤CT表现有特点，发现其典型CT表现，应考虑到平滑肌瘤的可能，但确诊仍有赖于病理检查。
Objective To analyze CT features of pulmonary leiomyoma （PL）, and to improve the diagnostic accuracy of PI.. Methods CT findings and clinical characteristics of 6 patients with PL proved by operation and pathology were retro- spectively analyzed, and the related literatures were reviewed. Results 6 cases were single, all tumors were 3.0-8.5 cm in diameter, the form all presented Circular or oval. and the edge was very smooth. On CT plain scan, all PI. lesions were moderate density; After intravenous contrast administration, 4 cases had homogeneous moderate enhancement and 2 cases had inhomogeneous enhancement; Solid lesion of 1 case was in density with formation of obvious patchy enhancement and necrosis lesions had no enhancement, 1 case presented annular enhancement, mediastinal lymph nodes had no obvious en largement. Conclusion The CT images with PL are characteristic. We should think about the diagnosis of PL when we find the typical CT manifestations. But the final correct diagnosis still depends on pathological examination.
