摘　　要：目的：探讨孤立性肺结核瘤（SPT）的 CT 表现。方法：回顾性分析26例经病理确诊的 SPT患者的 CT 资料，所有患者均做了胸部 CT 平扫，其中15例加做增强扫描。结果：26个病灶中，左右肺各13个病灶，位于上肺尖后段及下肺背段共18个，其余部位 8个，病灶长径约3～54 mm，其中正确诊断为肺结核瘤7例，占27％，误诊为周围型肺癌15例，占58％，误诊为炎性假瘤3例，误诊为其他病变1例。结论：SPT 容易误诊为肺癌等病变，CT 引导下经皮肺穿刺活检是确诊的有效方法。Objective： To analyse the CT finding of solitary pulmonary tuberculoma. Methods： CT data of 26 cases proved of SPT by pathology were retrospectively analyzed. All patients were underwent chest CT scan.8 cases of those were performed by enhanced scan together. Results： Of 26 lesions, there were 13 lesions distributed in left lung and right lung respectively.18 lesions were distributed in the upper lung of apical posterior segment or below lung of dorsal lung segment.8 lesions were distributedin other segments. The long diameters of these lesions were between 3-54 mm. We got definite diagnosis of pulm-onary tuberculoma of 7 cases （27%）, misdiagnosed 15 cases （58%） as per-ipheral lung cancer, and misdiagnosed 3 cases as inflammatory pseudot-umor, and misdiagnosed 1 case as other lesion. Conclusion： Solitary pul-monary tuberculoma could misdiagnose as lung cancer or other lesions. CT-guided percutaneous lung biopsy is an effective method for diagno-sis of pulmonary tuberculoma.
