空洞型肺转移瘤的影像诊断与临床分析

Imaging Diagnosis and Clinical Analysis of Cavitary Pulmonary Metastasis

目的分析空洞型肺转移瘤影像学表现,提高对其影像学特点的认识。方法回顾性分析21例有原发病灶并经手术病理证实的空洞型肺转移瘤病例,其中原发肿瘤位于肺7例,位于胃和肾各2例,位于鼻咽、喉、食管、结肠、膀胱、子宫颈管、胎盘滋养叶细胞、前列腺、乳腺、甲状腺各1例,并对其X线平片和CT片进行分析。结果空洞型转移瘤以肺内圆形类圆形结节内合并空洞较多见,可为厚壁、薄壁或不规则形。结论影像学检查,尤其CT检查对空洞型肺转移瘤诊断有较重要价值。

Objective To study the imaging diagnosis of cavitary pulmonary metastasis and improve the accuracy of diagnosis. Methods The X-ray and CT signs of cavitary pulmonary metastasis were analyzed. The original cancers were proved by surgery and pathology. Of 21 cases, the primary tumor in lung were 7 cases, stomach 2 cases, renal 2 cases, nasopharynx 1 case, larynx 1 case, esophagus 1 case, colon 1 case, vesica urinaria 1 case,canalis cervicis uteri 1 case, placental site trophoblastic 1 case,pros- tate 1 case,mamma 1 case, glandula thyreoidea 1 case. Results Cavitary pulmonary metastasis were characterized by nodules and cavernous of the metastatic tumour and the cavernous were thick wall or thin wall. Conclusion .Imaging diagnosis especially CT examination was valuable for cavitary pulmonary metastasis.
