| 摘 要： | 目的评价CT增强扫描环形强化征对肺结核瘤的诊断价值。方法 病理或临床证实的肺结核瘤21例，肺癌13例，炎性假瘤8例，均行CT平扫加增强扫描，分析病灶强化程度及强化形态。上述病例中肺结核瘤8例，肺癌13例，炎性假瘤4例经手术治疗，切除标本病理检查，分析标本血管数目与分布，将病灶CT扫描强化程度及强化形态与病灶内血管数目和分布作对照分析。结果 环形强化征仅见于肺结核瘤，结核瘤中央干酪性坏死，周边纤维包膜下含有血管结构丰富的肉芽组织是环形强化的病理基础。结论 环形强化征是肺结核瘤CT增强的形态特征，对结核瘤的论断具有肯定价值。

| Abstract: | Objective To evaluate the diagnostic value of annular enhancement sign on enhanced CT scans in tuberculoma. Methods The patients pathologically and clinically confirmed including pulmonary tuberculoma(n=21)and pulmonary carcinoma(n=13)and inflammatory nodules(n=8) were studied with plain chest CT scanning and enhanced scanning to observe the enhancement degree and pattern. Part of above including pulmonary tuberculoma(n=8)and pulmonary carcinoma(n=13)and inflammatory nodules(n=4)were reselected to examine pathologically the degree and pattern of vascularity. The image and pathology were contrasted. Results :The annular enhancement sign was based on cheesy necrosis inside the tuberculoma and the granuloma with great vascularity under the circled membrane, and was merely observed in tuberculoma. Conclusion The annular enhancement sign on enhanced CT scans is one characteristic of pulmonary tuberculoma,and is of high value in the diagnosis of pulmonary tuberculoma. |
