A two-year-old male poodle, diagnosed initially with primary portal vein hypoplasia was presented four months later with anorexia and dyspnoea. Clinical examination revealed shortness of breath, orthopnoea, muffled heart sounds and absence of normal lung sounds. Thoracic radiographs showed bilateral pleural effusion. Fluid analysis led to a diagnosis of chylothorax. After initial stabilisation, all possible causes of chylothorax were ruled out except for an idiopathic aetiology. This is the first case of chylothorax associated with primary hypoplasia of the portal vein.
