肺癌类型及分化程度与癌性空洞表现的关系

目的分析肺癌空洞的X线平片、CT与MRI表现,探讨空洞与肿瘤类型及分化程度关系.材料与方法对40例以各种方法证实为肺癌,均摄X线平片,其中30例做CT、10例做MRI检查.40例中30例手术病理检查,病理结果与影像表现对照.结果空洞内缘不规则似癌梁样改变,空洞壁厚度与空洞在肿瘤中位置特别是肿瘤越小,形成的空洞越小;肿瘤越大,空洞偏大,且肿瘤又呈分叶样改变等与肿瘤类型与分化程度有明显关系.CT对空洞内缘与肿瘤边缘显示优于X线平片.MRI对肿瘤组织信号强度变化,如肿瘤液化坏死,甚至对肿瘤性质有潜在定性能力.结论肺癌空洞X线、CT与MRI表现与肿瘤类型及分化程度有明显联系.

The Relationship between Appearances of Cancerous Cavity and Lung Cancer Types and Grading

Purpose:To study the relationship between cancerous cavity and Pulmonary neoplasm types and grading by analysis the find ing of cancerous cavity on X-ray film, CT and MRI. Materials and Methods: 40 cases of pulmonary carcinoma proved by pathological exam ination with plain film were included in this study. Among them, 30cases underwent CT scanning and 10 cases underwent MRI examina tion. Surgery procedures were performed on 30 cases, surgical-pathological finding were compared with imageology appearance. Results: Mor phological features of cancerous cavity had significant relationship with types and grading of pulmonary neoplasm, such as irregular inner bor der ofcavity, thickness of cavity wall and the position of cavity in mass. CT was better than plain film in displaying the inner and outer bor der of canoerous cavity. The changes of MRI signal intensity of neoplasm tissue, such as liquefaction and necrosis in tumor, would be helpful in differential the nature of naplasm. Conclusion: X-ray film, CT and MRI findings of cavity in lung cancer have significant relationship with tumor type and grading.
