The livers of 11 cows with a hepatic abscess were examined ultrasonographically. An abscess was observed in only one intercostal space in three cows, in two spaces in five, in three spaces in two, and in four adjacent intercostal spaces in one cow. In three cows the abscess was imaged in the caudodorsal aspect of the liver in the 11th and 12th intercostal space, in five cows the abscess was visible in the central part of the liver in the ninth and 10th intercostal space and in the three other cows the abscess was observed in the cranioventral region of the liver in the sixth, seventh and eighth intercostal spaces. The abscess had a distinct and well developed capsule in nine cows. The content of the abscess was echogenic in six cows, anechoic in two, and echogenic with hyperechoic foci in three. In four cows, the content of the abscess was partitioned by echogenic septa. In one cow, the echogenic content of the abscess was surrounded by a narrow anechoic rim of fluid. The diameter of the abscess was 5 to 10 cm in four cows, 11 to 15 cm in four, and more than 15 cm in three. In every case the diagnosis was confirmed by centesis and aspiration of the abscess which yielded pus. Ten of the cows were slaughtered after being examined and the ultrasonographic findings were confirmed. In addition, 10 of the cows had other lesions which included traumatic reticuloperitonitis, abscessation of the reticulum, thrombosis of the caudal vena cava, bronchopneumonia with abscessation, reticulo-omasal stenosis, ascites and suppurative omental bursitis.
对11头患有肝脓肿的奶牛肝脏进行了超声检查。在3头奶牛中，仅在一个肋间间隙观察到脓肿；5头奶牛在两个肋间间隙有脓肿；2头奶牛在三个肋间间隙有脓肿；1头奶牛在四个相邻的肋间间隙有脓肿。在3头奶牛中，脓肿位于肝脏第11和第12肋间间隙的尾背侧；5头奶牛的脓肿可见于肝脏中部第9和第10肋间间隙；另外3头奶牛的脓肿位于肝脏头腹侧区域第6、7和8肋间间隙。9头奶牛的脓肿有明显且发育良好的包膜。6头奶牛脓肿内容物呈回声；2头奶牛呈无回声；3头奶牛的脓肿内容物呈回声并伴有高回声灶。4头奶牛的脓肿内容物被回声隔分隔。1头奶牛的脓肿回声内容物被狭窄的无回声液体边缘包围。4头奶牛脓肿直径为5至10厘米，4头为11至15厘米，3头超过15厘米。每例均通过脓肿穿刺抽液确诊为脓肿，抽出脓液。10头奶牛在检查后被屠宰，超声检查结果得到证实。此外，10头奶牛还有其他病变，包括创伤性网胃腹膜炎、网胃脓肿、尾腔静脉血栓形成、伴有脓肿的支气管肺炎、网瓣胃狭窄、腹水和化脓性网膜囊炎。
