Fig. 2

Transverse (a), sagittal (b) and dorsal (c) plain computed tomographic multiplanar reconstruction images of the same dog diagnosed with renal cyst in Fig. 1. Multiple, non-contrast enhancing, well-defined, ovoid structures of variable size and of fluid attenuation are visible within the cortex and medulla of both kidneys. The caudal pole of the right kidney contains a very large, ovoid, thin-walled, non-contrasting enhancing structure of fluid attenuation that has replaced the normal architecture of its caudal third. For figures (a) and (c), the left side of the dog is at the right side of the images. Images courtesy of Dr. Mullins
