A 6 Months old holstein female dairy calf was referred to the clinic of veterinary medicine, Ferdowsi university
of Mashhad in the spring of 2011. The owner’s chief complaint was anorexia and growth retardation. Clinical
examination revealed depression, tachycardia, tachypenia, atonic rumen, weakness, recumbency, increase breath
sounds with harshness, cardiac murmur (Left side of the chest, base of heart with mild to moderate intensity),
jugular vein distention, submandibular and brisket edema. Haemogram profles showed an acute infection with
degenerative immune system response. Radiological fndings were consisted of increased radiopacity and alveolar
pattern (air bronchogram) in cranioventral lung lobes. Thoracic and abdominal ultrasonography was performed.
Anechoic free ﬂuids in pleural and abdominal cavity were observed which indicated pleural and peritoneal
effusion, respectively. According to these fndings and a survey on serum biochemical profle, with measuring the
concentration of serum troponin I and rule out other causes of edema and ascites, the cor Pulmonale associated with
bronchopneumonia was diagnosed. The sick animal was treated by parenteral antibiotic, diuretic and supportive
drugs. About 2 weeks after the treatment, clinical examination, radiological and ultrasonographical observations
and haemogram profles indicated complete recovery. Three months after the initial presentation, the calf was
visited again and the only problem was growth retardation that may be due to bronchopneumonia outcome.
