圆形(假瘤样)肺不张(或称胸膜瘤、折叠肺)是一种在胸膜渗出液和胸膜瘢痕基础上发生的较罕见的良性炎症病变,但往往易误诊为支气管癌或胸膜瘤。本文报告了3例圆形肺不张病人的典型表现,并对其诊断和鉴别诊断进行了讨论。例1 男,78岁。有吸烟史和石棉接触史。胸片示右肺中叶肿块阴影,右肺门淋巴结增大,同时伴有显著的胸膜肥厚。开胸发现右胸腔有100ml清亮液体,未触及明显的包块,肺门淋巴结轻度增大。胸膜活检有炎性变。
Circular (pseudotumor) atelectasis (or pleomorphosis, folded lung) is a rare benign inflammatory disease that develops on the basis of pleural exudate and pleural scars but is often misdiagnosed as bronchial carcinoma or pleural tumor. This article reports the typical findings of 3 patients with round atelectasis and discusses their diagnosis and differential diagnosis. Example 1 male, 78 years old. Have a history of smoking and asbestos exposure. The chest radiograph shows the shadow of the right middle lobe mass and the right hilar lymph node enlargement accompanied by significant pleural hypertrophy. Thoracotomy found 100ml clear liquid right chest, did not reach the obvious mass, slightly increased hilar lymph nodes. Pleural biopsy with inflammatory changes.
