A 52-year-old man admitted to our hospital with a pulmonary nodule detected by chest X-ray. Painless mass was located on the right anterior chest below the right clavicle, but enlarged recently. Chest computed tomography (CT) and magnetic resonance imaging (MRI) showed the hourglass shaped mass penetrating his right 2nd intercostal muscle, and growing to intra- and extra-thoracic areas. 60 x 40 x 50 mm in size. His laboratory findings were almost within normal ranges. We performed resection of the tumor and partial resection of the 2nd and 3rd ribs with a help of thoracoscopy. Pathological diagnosis was "intramuscular lipoma-infiltrating type, no malignancy". Assistance of thoracoscopic approach was found to be useful for complete resection of the tumor existing intra- and extra-thoracic areas.
一名52岁男性因胸部X线检查发现肺部结节入住我院。无痛性肿块位于右锁骨下右前胸，近期增大。胸部计算机断层扫描（CT）和磁共振成像（MRI）显示肿块呈沙漏形，穿透右侧第2肋间肌，并向胸腔内和胸腔外区域生长，大小为60×40×50mm。他的实验室检查结果几乎在正常范围内。我们在胸腔镜辅助下进行了肿瘤切除及第2、3肋骨部分切除。病理诊断为“肌内脂肪瘤浸润型，无恶性”。发现胸腔镜手术有助于完整切除胸腔内和胸腔外区域的肿瘤。
