3y FS Vizsla with recurrent lipoma after surgery. Images are ordered from cranial to caudal. There is a large, lobular fat‐attenuating mass
in the left inguinal region. The mass separates and distorts the relationship of the internal and external oblique muscles and the rectus
abdominis muscle (a: arrows). Widening and infiltration of the internal oblique muscle is visible in the center of the muscular discontinu­
ity (a: asterisk). The more dorsal arrow denotes a region of muscular irregularity. The abdominal musculature is more regular in the caudal
aspect of the mass (b: arrows).

12y MC Labrador Retriever cross with a
suspected splenic mass based on abdominal
palpation. There is a large mass with a thick,
regular capsule in the right cranial abdomen.
The inner portion of the mass is heterogeneous
soft‐tissue attenuating material surrounded
by fat. On contrast‐enhanced images, the cap­
sule of the mass is moderately enhancing.
Histopathology showed a fibrous capsule with
internal fat necrosis and hemorrhage.
