Today’s case is a 13-year-old male neutered Miniature Schnauzer with recurrent cystic calculi.
There is a fat density mass with a thin rim of soft tissue opacity in the left dorsal and caudal abdomen. It is visible on the lateral projection ventral to L2-L7, and on the v/d between the spleen and left ilium.
The decreased radiopacity of the mass compared to soft tissue is the key to diagnosing a lipoma. This is a benign and incidental lesion.
