Thoracic radiographs of nine cats with confirmed bronchoalveolar carcinoma (BAC) were reviewed retrospectively. Radiographic appearance of BAC was divided into three categories: mixed bronchoalveolar pattern, ill-defined alveolar mass, or mass with cavitation. In addition to these radiographic signs, all nine cats had evidence of some form of bronchial disease. Cavitary lesions were the most common finding (n = 5). In addition, three cats in this category had diffuse bronchointerstitial opacity and one cat had focal peribronchial cuffing. Five cats had either a mixed bronchoalveolar pattern with bronchiectasis (n = 3) or an ill-defined alveolar mass with peribronchial cuffing (n = 2). One cat had both a mixed bronchoalveolar pattern and a cavitary mass. Each of these nine cats had some form of bronchial disease (bronchointerstitial pattern, peribronchial cuffing, or bronchiectasis), which aids in the radiographic diagnosis of bronchoalveolar carcinoma and may represent airway metastasis.
对9只确诊为支气管肺泡癌（BAC）的猫的胸部X光片进行了回顾性分析。BAC的影像学表现分为三类：混合性支气管肺泡型、边界不清的肺泡肿块或有空洞的肿块。除了这些影像学表现外，所有9只猫均有某种形式的支气管疾病证据。空洞性病变是最常见的表现（n = 5）。此外，该类别中有3只猫有弥漫性支气管间质模糊，1只猫有局灶性支气管周围套袖征。5只猫表现为混合性支气管肺泡型伴支气管扩张（n = 3）或边界不清的肺泡肿块伴支气管周围套袖征（n = 2）。1只猫同时有混合性支气管肺泡型和空洞性肿块。这9只猫每只都有某种形式的支气管疾病（支气管间质型、支气管周围套袖征或支气管扩张），这有助于支气管肺泡癌的影像学诊断，可能代表气道转移。
