Diaphragmatic herniation of the liver in macaques demonstrated by intravenous hepatography.

A suspected diagnosis of diaphragmatic herniation of the liver in 2 monkeys (Macaca fascicularis and Macaca mulatta) was confirmed radiographically by using various contrast media. Experimental compound AG 60.99, which is selectively concentrated in the liver and spleen, allowed excellent visualization of these 2 organs and confirmed the presence of a portion of the liver in the right thorax. Cholografin Meglumine was subsequently utilized to determine the location of the gall bladder. Other potential uses for AG 60.99 were discussed.
