case_images: Due to the depth of the mass and concern for a potential sarcoma or another tumor, magnetic resonance imaging (MRI) was ordered, which showed a fat hernia from the left perirenal space through the left flank of the posterior lateral abdominal wall most consistent with a Grynfeltt type hernia of the superior lumbar triangle (Figure 1).
