当部分正面看到胸膜外肿块时，它可能类似于肺实质病变。然而，不完整边界的存在是了解质量真实本质的线索。 1 病例报告 一名21岁男性，常规胸部X线片（后前位片）显示左侧中肺野较大病灶，侧面边界征不完整，提示胸膜外肿块（图1）。斜位片显示胸膜外肿块的典型体征（图2）。第四肋骨出现破坏性变化证实了其胸膜外位置。该病变似乎起源于肋软骨交界处的第四肋骨。术前诊断为肋骨软骨肉瘤；这在手术中得到了证实。肿瘤连同第三和第五肋骨被完全切除。用聚四氟乙烯网封闭了手术缺损，患者平安无事
WHEN an extrapleural mass is seen partially en face , it may simulate a pulmonary parenchymal lesion. However, the presence of an incomplete border is a clue to the true nature of the mass. 1 Report of a Case A routine chest x-ray film (posteroanterior view) of a 21-year-old man showed a large lesion in the left midlung field with an incomplete border sign laterally, indicating an extrapleural mass (Fig 1). The oblique view showed typical signs of an extrapleural mass (Fig 2). The presence of destructive changes in the fourth rib confirmed its extrapleural location. This lesion appeared to arise from the fourth rib at the costochondral junction. The preoperative diagnosis was a chondrosarcoma of the rib; this was confirmed at surgery. The tumor was completely removed en bloc, along with the third and fifth ribs. The surgical defect was closed with Teflon mesh, and the patient made an uneventful
