An 8-year-old, Patterdale terrier was referred for evaluation of tachypnoea, exercise intolerance, and weight loss. Computed tomographic images showed pneumomediastinum, diffuse pulmonary ground glass opacity, and marked dilatation of peripheral bronchi, but no evidence of thickened bronchial walls. The histopathologic diagnosis was diffuse pulmonary interstitial fibrosis, type II pneumocyte hyperplasia, and bronchiectasis. The lack of evidence of primary bronchitis supported a diagnosis of traction bronchiectasis. Traction bronchiectasis can occur as a sequela to pulmonary fibrosis in dogs.
一只8岁的派特戴尔梗犬因呼吸急促、运动不耐受和体重减轻前来接受评估。计算机断层扫描图像显示纵隔气肿、弥漫性肺磨玻璃样混浊以及外周支气管明显扩张，但未发现支气管壁增厚的迹象。组织病理学诊断为弥漫性肺间质纤维化、II型肺细胞增生和支气管扩张。缺乏原发性支气管炎的证据支持牵拉性支气管扩张的诊断。牵拉性支气管扩张可作为犬肺纤维化的后遗症出现。
