13 year old DLH cat

February 28, 2019 By Allison Zwingenberger

This week’s case is a 12-year-old female neutered Domestic long haired cat with episodes of coughing and weight loss for the last three months. This is a challenging pulmonary pattern. What do you think it is?

Findings

On radiographs of the thorax, there is a diffuse, bronchointerstitial pattern with a nodular component. The lung lobes are rounded and retracted, with increased opacity in the pleural space. The cardiac silhouette is somewhat obscured but appears normal in size.

Differential Diagnosis

  • Diffuse bronchointerstitial and nodular pattern may be caused by chronic lower airway disease, inflammatory disease, or neoplasia. The pleural component suggests effusion or soft tissue in the pleural space.

Diagnosis

Ultrasound guided fine needle aspirate of a pulmonary nodule was performed, and adenocarcinoma with inflammatory and neoplastic effusion was diagnosed on cytology.
