| 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 < 0101) 。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,强化的程度和方式与结节的病理组
织学相关。 |

| Purpose 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 < 0101) 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 pathologichistology of BSPNs. |
