AI Article Synopsis
- A 51-year-old woman presented with pericardial effusion, which was later found to be caused by an inferior middle mediastinal mass resembling lymph node disease.
- Surgical intervention via thoracotomy revealed that the tumor was invading the posterior atrial wall, but complete resection was successfully achieved with the help of extracorporeal circulation.
- The tumor was identified as a rare soft tissue myoepithelioma, and despite the challenges in surgery, the prognosis is favorable since it showed no signs of malignancy.
Article Abstract
An inferior middle mediastinal mass was observed in a 51-year-old woman initially presenting as pericardial effusion and mimicking lymph node disease. Thoracotomy demonstrated a tumor invading the posterior atrial wall. Complete resection was possible under the extracorporeal circulation. The tumor proved to be a soft tissue myoepithelioma in an exceptional location. Despite the difficult surgical resection due to location, prognosis of this absolutely rare tumor without cytologic features of malignancy should be good.
