Small Animal Radiology and Ultrasound: A Diagnostic Atlas and Text

214 Small Animal Radiolo g y and Ultrasono graphy
Fig. 2-196 A 12-year-old neutered female domestic short-haired cat
had a mild (grade 2/6) systolic murmur. The ventrodorsal view
revealed a 1-cm diameter mass in the left caudal lung lobe (arrow).
The cardiac silhouette was within normal limits. The ascending aorta
(a) is seen very clearly. This finding occasionally is seen in older cats
with “lay-down” (i.e., cranial rotated along the sternum increasing
sterna contact) hearts. Diagnosis: Bronchogenic carcinoma.
Fig. 2-197 An 11-year-old neutered male domestic short-haired cat
had lameness and swelling of the digits of the right front foot. The
ventrodorsal view of the thorax reveals multiple, poorly marginated
tissue densities (arrows) in multiple lung lobes. Diagnosis:
Bronchogenic carcinoma with metastasis to the toes of the right front
foot.
