5y FS Cattle Dog cross with progressive cough following heartworm disease treatment. Images b and c have been reformatted in oblique
planes paralleling the path of the right and left pulmonary artery, respectively. Contrast‐enhanced CT images acquired during the vascular
phase reveal discrete hypoattenuating filling defects within the right (b) and left (c) pulmonary arteries, consistent with chronic pulmo-
nary thromboembolism (a–c: arrowheads). The dog also had concurrent metastatic carcinoma resulting in multiple pulmonary masses
and nodules and thoracic lymphadenopathy (a–c).

was seen as an incidental finding (arrowheads).
