Abstract: | The radiographic findings in 41 feline primary lung tumors are reported. Case material includes 29 adenocarcinomas, six bronchiolog-alveolar carcinomas, and six squamous cell carcinomas. Adenocarcinomas tended to occur as focal, solitary, well-circumscribed masses (eight cats), as localized consolidations (six cats), or as multiple, poorly circumscribed masses (five cats). Bronchiolo-alveolar cell carcinomas and squamous cell carcinomas were radiographically pleomorphic. Calcification was recognized in only five cats, four with adenocarcinomas and one with bronchiolo-alveolar carcinoma. Cavitation was identified in seven adenocarcinomas, one squamous cell carcinoma, and one bronchiolo-alveolar carcinoma. Nearly 50% (20 cats) of the patients had radiographic evidence of pleural involvement. Fifteen cats had evidence of regional lymph node involvement. |
