The clinical, ultrasonographic and radiographic findings in three cows and one bull with pleuropneumonia are described. All the animals had fever, indigestion, tachypnoea and abnormal lung sounds. Percussion of the thoracic wall elicited signs of pain and tests for foreign bodies were positive. Ultrasonographic examination revealed an accumulation of anechogenic to hypoechogenic fluid in the pleural space in the ventral thorax of all the animals. In one animal, echogenic bands of fibrin were observed between the thoracic wall and pulmonary surface. In another, parts of the right lung were not inflated because of severe bronchopneumonia. Radiographic examination revealed a pleural effusion, apparent as a horizontal fluid line, in three animals. In addition, the increased radiopacity in parts of the dorsal lung fields and increased bronchial and peribronchial markings suggested bronchopneumonia. In three animals, the radiographs revealed linear foreign bodies in the reticulum, suggesting that the pleuropneumonia was caused by the penetration of the foreign body into the thoracic cavity. A diagnosis of pleuropneumonia was made in all the animals on the basis of the clinical, ultrasonographic and radiographic findings and the analysis of the pleural fluid. The diagnosis was confirmed at slaughter in three of them; the fourth animal was treated and was clinically healthy when it was discharged.
描述了三头奶牛和一头公牛患胸膜肺炎的临床、超声和放射学检查结果。所有动物均有发热、消化不良、呼吸急促和肺部异常声音。叩击胸壁有疼痛体征，异物检查呈阳性。超声检查显示所有动物胸腔腹侧胸膜腔内有无回声至低回声液体积聚。在一只动物中，在胸壁和肺表面之间观察到纤维蛋白的回声带。在另一只动物中，由于严重支气管肺炎，右肺部分未充气。放射学检查显示三只动物有胸腔积液，表现为水平液线。此外，背侧肺野部分的放射密度增加以及支气管和支气管周围纹理增多提示支气管肺炎。在三只动物的X光片中发现网胃内有线性异物，提示胸膜肺炎是由异物穿透进入胸腔引起的。根据临床、超声和放射学检查结果以及胸腔积液分析，对所有动物做出了胸膜肺炎的诊断。其中三只在屠宰时确诊；第四只动物接受了治疗，出院时临床健康。
