肠道阿米巴原虫感染在本地区农村较为常见,其并发症肝脏及胸腔阿米巴病也并非罕见。以往,我们总结的胸腔阿米巴病(中国防痨杂志5∶389,1964)均指继发者,即阿米巴原虫由肝脏直接穿过横膈而侵犯胸腔,其肺部病变都在右下野,并都有右侧横膈抬高,运动受限,同侧胸膜反应,于气腹后则见肝膈有明显粘连等特征(如图1,本文图见封底),再结合临床情况,一般诊断并不困难。所谓原发性胸腔阿米巴病实系原虫经血路传播至胸腔致病者,一般认为多由直肠下段经中、下痔静脉,入下腔静脉、右心而至肺,其肺部病变不一定局限于右下野,而可分布于两肺任何部位,因此其误诊可能远比继发性者为大。本 Intestinal amebic protozoal infections are more common in rural areas of the country, and complications of liver and pleural amebiasis are not uncommon. In the past, we conclude that pleural amebiasis (Chinese Journal of Prevention and Cure Diseases 5:389, 1964) refer to the secondary, that is, the amoeba by the liver directly through the diaphragm infringe the chest, the lung lesions are right Down, and have the right diaphragm elevation, limited movement, ipsilateral pleural reaction, see after the pneumoperitoneum pneumoperitoneum obvious adhesions and other characteristics (Figure 1, this article see the back cover), combined with clinical conditions, General diagnosis is not difficult. The so-called primary pleural amebiasis is the protozoal parasite transmitted by the bloodstream to the chest pathogenic disease is generally believed that the lower rectum by the lower hemorrhoid veins, into the inferior vena cava, right heart to the lungs, the lung disease is not Must be limited to the lower right field, but can be distributed in any part of the lungs, so its misdiagnosis may be far larger than secondary. this
