Although the presence of a pleural effusion is almost always indicative of an intrathoracic problem reflection will yield a certain number of extrathoracic causes, such as hypoproteinemia, Meigs' syndrome pancreatitis and subphrenic abscess. The kidney is a close neighbor of the diaphragm and pleural cavity, and a case of renal stone associated with a small ipsilateral pleural effusion, which regressed with resolution of the primary process, is reported.
尽管胸腔积液的存在几乎总是提示胸腔内存在问题，但仔细检查仍会发现一些胸腔外原因，如低蛋白血症、梅格斯综合征、胰腺炎和膈下脓肿。肾脏是膈肌和胸腔的紧邻器官，本文报告一例肾结石伴同侧少量胸腔积液的病例，该胸腔积液在原发疾病治愈后消退。
