目的探讨CT检查在肺母细胞瘤诊断中的应用价值。方法搜集经针吸活检、手术病理证实的肺母细胞瘤10例,对其临床资料及CT表现进行回顾性分析。结果10例肿瘤9例位于周边肺胸膜下,即周围型,1例为中央型。10例中,右肺6例,其中上叶1例、中叶1例、下叶4例;左肺上叶3例,下叶1例。肿瘤较大,直径均>3cm,瘤体中液化坏死7例,增强扫描明显强化。肺门和纵隔淋巴结肿大1例、骨质破坏1例及远处转移2例。结论肺母细胞瘤CT表现缺乏特异性,认真分析并辅以CT导向下针吸活检有助于肺母细胞瘤的诊断。
Objective To investigate the value of CT in the diagnosis of pulmonary blastoma. Methods Ten cases of pulmonary blastoma confirmed by needle biopsy and pathology were collected and their clinical data and CT findings were retrospectively analyzed. Results Nine of the 10 tumors were located in the peripheral pulmonary pleura, ie, the peripheral type, and one was the central type. In 10 cases, there were 6 cases of right lung, including 1 case of upper lobe, 1 case of middle lobe, 4 cases of lobe, 3 cases of upper left lobe and 1 case of lobe. Large tumors, diameter> 3cm, tumor liquefaction necrosis in 7 cases, enhanced scan was significantly enhanced. Hilar and mediastinal lymph nodes in 1 case, 1 case of bone destruction and distant metastasis in 2 cases. Conclusion The CT appearance of pulmonary blastoma is not specific. A careful analysis and supplemented CT guided needle biopsy can be helpful for the diagnosis of pulmonary blastoma.
