A 7-month-old male Pomeranian had severe dyspnea for 2 weeks. The lateral bronchogram showed a stenosis of the trachea. Inspite of supportive therapy including supplemental oxygen, the dog died 5 days later. Six pedunculated nodules were recognized in the mucosal surface of the trachea at necropsy. The tracheal nodules were histopathologically granuloma characterized by many coiled parasites containing a little collagen fibers, lymphocytes, plasma cells and macrophages. Female parasites had a lot of embryonated eggs in the uterus. Immature worms were observed in the dilated lymph vessels of bronchial and bronchiolar wall in the lungs. The worms were identified as Filaroides osleri based on the parasitological examinations.
一只7个月大的雄性博美犬出现严重呼吸困难达2周。侧位支气管造影显示气管狭窄。尽管采取了包括补充氧气在内的支持性治疗，但这只狗5天后死亡。尸检时在气管黏膜表面发现6个带蒂结节。气管结节的组织病理学表现为肉芽肿，其特征是有许多盘绕的寄生虫，含有少量胶原纤维、淋巴细胞、浆细胞和巨噬细胞。雌性寄生虫子宫内有许多已受精的虫卵。在肺支气管和细支气管壁扩张的淋巴管中观察到未成熟的蠕虫。根据寄生虫学检查，这些蠕虫被鉴定为奥氏丝虫。
