A 46-year-old woman with a history of endometrial sarcoma underwent hysterectomy, bilateral salpingo-oophorectomy, and radiotherapy. She remained well clinically during follow-up. However, 18 months later she complained of shortness of breath and chest discomfort. A chest roentgenogram revealed a massive right pleural effusion and mediastinal shift to the left (Fig 1). A computed tomographic scan of the thorax confirmed a heterogeneous mass measuring 10 x 15 x 18 cm with a large pleural effusion in the right hemithorax causing compression of the right lung and a mediastinal shift to the left (Fig 2). On positron emission tomography, the lesion had a standard uptake value maximum of 6.35 (Fig 3). No other positron emission tomographic positive lesion was seen. The findings were consistent with pleural metastasis.
She underwent elective right pneumonectomy through a median sternotomy with a right thoracotomy extension. A 2.2 kg pneumonectomy specimen with adjoining tumor was delivered. Histology confirmed a high-grade sarcoma. Postoperatively she made an uneventful recovery and was discharged home on postoperative day 11.
