English: Video recording 5. The heifer calved unaided four weeks previously. Appetite is markedly reduced and the cow refuses the concentrate component of the ration. The flanks are very sunken suggesting a reduced appetite. The heifer has been dried off due to the very low milk yield. The rectal temperature is 38.8°C. The heifer is dull and depressed and often stands with the neck extended and the head held lowered. There is occasional coughing. A purulent nasal discharge is present in both nostrils. The respiratory rate is increased to around 40 breaths per minute with an abdominal effort. There are no other significant clinical findings. As the probe head is advanced ventrally from normal lung tissue present in the dorsal lung field, the first ultrasonographic change in lung parenchyma is the pronounced columnar irregularity of the hyperechoic linear echo of the normal visceral (pulmonary) pleura in the antero-ventral apical and cardiac lung lobes. The dorsal margin of the lung pathology commences 15–20 cm above the point of the elbow at the 6th and 7th intercostal spaces and extends from this level to the ventral margin of the lung lobes. These hypoechoic “columns” extend up to 8 cm from the visceral pleura and are bordered distally by bright hyperechoic lines as the sound waves contact either normal aerated tissue or smaller airways deeper within the lung tissue. Ventrally, ultrasonographic examination images the diseased lung as a large hypoechoic area containing multiple 5–10 mm wide hyperechoic lines which extend up to 8 cm into the lung parenchyma. In is possible to image the right lung and liver in the same field; diseased lung has the sonographic density of liver. This heifer failed to respond to antibiotic therapy due to the extensive nature of the suppurative bronchopneumonia. |
