| 摘 要： | 目的:分析气管主支气管原发平滑肌瘤的MSCT表现,以提高对其认识。方法:回顾性分析经病理证实的7例气管主支气管原发平滑肌瘤患者临床特征、CT表现及病理表现。结果:7例患者女性6例,男性1例,年龄19~65岁,均以非特异性呼吸道症状就诊。肿瘤位于气管主干2例,隆突1例,右主支气管1例,左主支气管3例。肿瘤大小0.6~2.0 cm。MSCT表现呈类圆形、椭圆形者6例,呈分叶形者1例。腔内生长型者6例,腔内外生长型者1例。7例CT平扫描密度均匀,未见钙化,增强扫描呈中等到明显强化者6例,轻度强化者1例。7例均未见明确坏死、囊变。7例均无纵隔淋巴结肿大及胸腔积液。伴阻塞性改变者2例。结论:气管主支气管原发平滑肌瘤的CT表现有一定的特征性,多表现为腔内生长的规则病灶、多强化明显。CT及后处理技术对显示肿瘤大小、范围及与邻近结构的关系有一定的价值。

| Abstract: | Objective: To discuss the MSCT features of central airway primary leiomyoma and improve the diagnostic ability of this disease. Methods: The MSCT findings, clinical characteristics and pathological findings of 7 patients with pathologically confirmed central airway leiomyoma were retrospectively analyzed. Results: 1 male and 6 females with age of 19 ~ 65 years old were included, all with nonspecific respiratory symptoms. There were 2 cases located in trachea, 1 case in carina, 3 cases in left main bronchus and 1 case in right main bronchus, with maximum diameter of 0.6 ~ 2 cm. MSCT showed the shape of tumors were round or oval in 6 cases and lobular in one case. 6 cases were entophytic growth type and 1 case was both entophytic and helophytic growth type. 7 cases of patients CT scan without contrast showed homogeneous density with no calcification or fat. Enhanced CT scan showed 6 cases with moderate to marked enhancement and 1 case with mild enhancement. No necrosis or cystic degeneration were observed in 7 cases, no meditational adenopathy or pleural effusion either. There were 2 cases with obstructive change. Conclusion: There are some features of central airway leiomyoma on MZCT such as regular tumor in the lumen, often demonstrate marked enhancement. CT and post processing techniques have a certain value in showing size, range and the relationship with adjacent structures of the tumor. |
