A seven-year-old intact male English rabbit, housed indoors, presents with acute onset tachypnoea and laboured breathing. There is a three-month history of weight loss, hindlimb weakness and rapid fatigue. The rabbit is alert, thin and weak. The mucous membranes are pale, with prolonged capillary refill time. A good response is noted to oxygen administration. The rabbit is sedated with intravenous midazolam and lateral and ventrodorsal radiographs of the thorax are taken.

What are the differential diagnoses in this case? | Congestive heart failure (myocardial, valvular and congenital disease) is seen in middle-aged to older rabbits. The weakness, weight loss and rapid fatigue observed, although non-specific signs, should arouse suspicion of cardiac or lower respiratory disease.

Based on the radiographic findings, what immediate treatment would you consider? | The radiographs show a pleural effusion. Immediate thoracocentesis will help stabilize the rabbit as well as determine the type of effusion.
In this case 20 ml of a serosanguinous fluid was obtained from both left and right sides of the chest. It was found to be a modified transudate with a protein of 22.4 g/l (2.4 g/dl) (ref: 25–30 g/l [2.5–3 g/dl]) and a nucleated cell count of 2 × 109/l (2000/μl) (ref: 1–7 × 109/l [1000–7000/μl]). No organisms were cultured. |
