Five cows with reticular abscesses were examined clinically, haematologically, radiographically and ultrasonographically. They all had clinical signs typical of traumatic reticuloperitonitis, including chronic indigestion, pyrexia, an absence of or reduced ruminal motility, weight loss and a positive reaction to foreign body test. A haematological examination revealed anaemia, increased concentrations of plasma protein and fibrinogen and a decreased clotting time in the glutaraldehyde test. On the basis of the radiographic examination, a tentative diagnosis of reticular abscess was made in four of the cows, because the reticulum was displaced from the peritoneum or because there was an extensive gas-fluid interface in the reticular region. By ultrasonography, a large reticular abscess with a well developed capsule was visible in each of the cows. The abscess was located between the reticulum and ventral peritoneum in two of them, between the reticulumn and right thoracic wall in two and between the reticulum and spleen in the other cow. A foreign body penetrating the abscess could be visualised ultrasonographically in one cow. In two cows, the abscesses were drained through an ultrasound-guided transcutaneous incision. In the other three cows, the abscess was incised and drained from within the reticulum during a rumenotomy. Ultrasonographic examination revealed that the abscess had been completely evacuated in four cows, but only by about two-thirds in the remaining cow. All the cows were clinically healthy when they were discharged.
对5头患有网胃脓肿的奶牛进行了临床、血液学、放射学和超声检查。它们均有创伤性网胃炎的典型临床症状，包括慢性消化不良、发热、瘤胃蠕动缺乏或减弱、体重减轻以及对异物试验呈阳性反应。血液学检查显示贫血、血浆蛋白和纤维蛋白原浓度升高以及在戊二醛试验中凝血时间缩短。基于放射学检查，4头奶牛被初步诊断为网胃脓肿，原因是网胃与腹膜分离或网胃区域存在广泛的气液界面。通过超声检查，每头奶牛均可见一个有完整包膜的大网胃脓肿。其中2头奶牛的脓肿位于网胃与腹侧腹膜之间，2头位于网胃与右胸壁之间，另一头位于网胃与脾脏之间。超声检查可在1头奶牛中看到一个穿透脓肿的异物。2头奶牛通过超声引导下经皮切开引流脓肿。另外3头奶牛在瘤胃切开术中从网胃内切开并引流脓肿。超声检查显示，4头奶牛的脓肿已完全排空，但其余1头奶牛仅排空了约三分之二。所有奶牛出院时临床均健康。
