The dog was diagnosed with spontaneous (atraumatic) hemothorax and stabilized. Contrast\u2010enhanced computed tomography (CT) of the thorax identified a large, aneurysmal dilation of a suspected collateral vascular structure in the mediastinum with a large thrombus in the dilatation, consistent with a recent rupture. In addition, multiple mineralized pulmonary arterial thrombi were identified. These findings were suggestive of chronic, thromboembolic pulmonary hypertension with suspected secondary acquired collateral circulation and subsequent aneurysmal dilatation and rupture of one of these structures, resulting in the bilateral hemothorax. The underlying cause of the thrombi was not identified despite an extensive workup. Upon resolution of the hemothorax, the dog was discharged with clopidogrel and has had no recurrence in 4\u00a0years.<\/jats:p><\/jats:sec>New or Unique Information Provided<\/jats:title>This is the first description of canine hemothorax possibly caused by the rupture of an aneurysmal dilation of suspected pulmonary hypertension\u2010related vascular collaterals in a dog.
