| 摘 要： | 目的分析肺错构瘤的CT表现,并提高其诊断准确性。方法 31例由病理证实的肺错构瘤患者均经16层螺旋CT胸部平扫与增强扫描。对所有患者肿瘤病灶的部位、形态、大小、数目及强化特征,进行了回顾性总结分析。结果 CT扫描证实,25例(81%)的错构瘤是肺内型,其中包括24例孤立型和1例多发型,4例合并周围型肺癌。另外6例(19%)的错构瘤是支气管腔内型。绝大多数(30/31)患者的肿瘤CT表现是以边缘光滑锐利的圆形或卵圆形、直径小于3 cm的肿块影为特征。此外,还可看到其他或多或少的伴发征象,诸如,规则的圆形或卵圆形结节(58%),不规则形结节(48%),软组织密度结节影(55%),钙化影(35%),以及脂肪密度影(13%)。在对比增强CT像上,所有错构瘤病灶均表现为轻度强化(强化值小于30 HU)。结论除钙化及脂肪密度外,边界清晰及增强后轻度强化是诊断肺内型错构瘤的重要依据。而支气管腔内结节出现钙化或脂肪密度则高度提示支气管腔内型错构瘤。 |

| Abstract: | Objective To analyze the CT findings of pulmonary hamartomas and to elevate the diagnostic accuracy.Methods Thirty-one patients with pathologically proved pulmonary hamartoma underwent precontrast and postcontrast 16-slice spiral CT(MSCT) scans of the chest.The site,shape,size,number and enhanced features of pulmonary hamartomas in all the patients were retrospectively summarized and analyzed.Results CT scans demonstrated that the hamartomas of 25(81%) cases were intrapulmonary type which comprised 24 solit... |
