To describe the radiologic findings in patients with primary bronchogenic carcinoma and pulmonary metastases at presentation.
A retrospective review of patients with bronchogenic carcinoma who at presentation had pulmonary metastases.
Fourteen (52%) men and 13 (48%) women with a mean age of 60 years were identified. Adenocarcinoma was the most common histology (70%). The number of nodules varied, although 78% of patients had greater than 50 nodules. Nodules size ranged from 2 to 30 mm, but 82% of patients had nodules less than 10 mm in diameter. Mediastinal lymphadenopathy was seen in 41% of patients, and pleural disease in 44% of patients. Only 37% had radiologic evidence of extrathoracic disease, with bone metastases (30%) being the most common.
Multiple pulmonary nodules may be the presenting thoracic manifestation of primary bronchogenic carcinoma, with patterns of metastases and survival rates similar to other stage IV patients.
描述原发性支气管肺癌伴肺转移患者初诊时的放射学表现。
对初诊时伴有肺转移的支气管肺癌患者进行回顾性研究。
共纳入14名男性（52%）和13名女性（48%），平均年龄60岁。腺癌是最常见的组织学类型（70%）。结节数量各不相同，不过78%的患者结节数超过50个。结节大小从2毫米至30毫米不等，但82%的患者结节直径小于10毫米。41%的患者可见纵隔淋巴结肿大，44%的患者有胸膜病变。只有37%的患者有胸外疾病的放射学证据，其中骨转移（30%）最为常见。
多发性肺结节可能是原发性支气管肺癌初诊时的胸部表现，其转移模式和生存率与其他IV期患者相似。
