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 analyze the imaging manifestations of cavitary pulmonary metastases and to improve their understanding of imaging features. Methods A retrospective analysis of 21 cases of primary lung lesions with confirmed pathological evidence of empty lung metastases, including 7 cases of primary tumor located in the lungs, located in the stomach and kidney in 2 cases, located in the nasopharynx, larynx, esophagus, colon, Bladder, cervical canal, placental trophoblast cells, prostate, breast and thyroid in 1 case, and its X-ray and CT films were analyzed. Results Holstein-type metastases in the lung circular round nodules with more common cavity, can be thick, thin-walled or irregular shape. Conclusion Imaging examination, especially CT examination of cavitary pulmonary metastases diagnosis of more important value.
