Rupture of a pulmonary abscess secondary to Dirofilaria immitis infection was the cause of acute pneumothorax in a dog. The dog was euthanatized because it did not respond well to treatment for pneumothorax. Postmortem examination revealed a mass in the right middle lung lobe and adult D immitis in the pulmonary artery. Histologic examination of the lungs revealed microfilariae, suppurative inflammation, thrombi, vasculitis, and fibrosis. Clinicians should include D immitis infection in the differential diagnosis of pneumothorax.
犬恶丝虫感染继发肺脓肿破裂是一只犬急性气胸的病因。该犬因对气胸治疗反应不佳而实施安乐死。尸检发现右中肺叶有一肿块，肺动脉内有成年恶丝虫。肺组织学检查显示有微丝蚴、化脓性炎症、血栓、血管炎和纤维化。临床医生在气胸的鉴别诊断中应考虑恶丝虫感染。
