Bronchogenic Adenocarcinoma with Intrapulmonary Metastases in a Domestic Shorthair Cat
A 12 year-old male castrated domestic shorthair cat was presented to Cornell University’s Hospital for Animals’ Internal Medicine service for a history of chronic coughing, weight loss, inappetence, and lethargy. He had an approximately 3 month history of coughing that was not paroxysmal and was productive with one episode of hemoptysis. He developed inappetence during this time. There were no changes in drinking, urination, or defecation. The patient lived with 6 other strictly indoor cats that showed no signs of illness. The patient had no travel history and was not receiving any medications. He was tested FeLV/FIV negative one year ago. The patient was referred to Cornell University for further work-up after diagnostic testing by the primary care veterinarian revealed unusual thoracic radiographs. On presentation, the patient was quiet, alert, and responsive with normal vital parameters and a body condition score of 3 out of 9. He had increased lung sounds bilaterally and mild serous ocular and nasal discharge. A right thyroid slip was also noted on exam. The remainder of his physical exam was unremarkable. The problem list for this patient included chronic coughing, weight loss, inappetence, lethargy, serous ocular and nasal discharge, and right thyroid slip. Differential diagnoses for this patient included neoplasia, infectious causes and/or inflammatory causes. Diagnostic testing for this patient included complete blood count, chemistry panel, urinalysis, baseline T4, thoracic radiographs, CT scan, and tracheal wash. This presentation will discuss the results of these diagnostic tests, prognosis, outcome, and an overview of the disease.
