摘要
目的 用动态CT评价良性孤立性肺结节 (BSPN)。方法 对 37例BSPN行动态CT增强扫描及病理对照分析。结果 结核球无强化或环形强化 ,镜下主要为干酪样坏死 ,炎性假瘤强化显著 ,持续时间较长 ,镜下见大量变性炎细胞和炎性肉芽组织 ,二者差异显著 (P <0 0 1)。错构瘤多不均匀强化。硬化血管瘤内有小血管灶性增生及瘤样扩张而表现为显著不均匀强化。结论 动态CT有助于BSPN的定性诊断 。
Puropose To evaluate benign solitary palmonary nodules (BSPNs) by using incremental dynamic enhanced CT. Methods In 37 patients with BSPNs confirmed by operation and pathology,Serial dynamic enhanced CT scans were performed and CT\|pathological correlative study were analysed. Results Tuberculomas showed no or ring enhancement which are mainly composed of caseous necrosis histologically.All inflammatory pseudotumors compared with tuberculomas were enhanced significantly ( P <0 01) because a mount of degenerative inflammtory cells and granulomatous tissues were appeared pathologically.Most hamartomas showed inhomogereous enhancement.Sclerosing hemongiomas showed markly inhomogereous enhancement because of the granulomatous tissue with marked vascularity. Conclusion Dynamic enhanced CT can improved the qualitative diagnosis of BSPNs.The enhanced extent and types are closely correlated with pathologic\|histology of BSPNs. [
