Which organ is abnormal in these radiographs from a 13-year-old male neutered cat?

Incorrect. You chose {selectedText}, but the correct answer is {correctText}.
The right kidney is markedly enlarged, with a rounded shape. It is distorting the abdominal wall on the v/d projection and displacing the ascending and transverse colon medially and ventrally. This was a perinephric pseudocyst, which is often associated with chronic renal disease, but is often asymptomatic in itself.
The left kidney also has an abnormal shape, with reduced length and increased width. There is also spondylosis deformans at the L5-6 intervertebral disc space, which is an incidental finding.
