case_images: In MRI defecography, an incidental left polypoid mid-rectal mass was located 7.6 cm from the anal verge, measuring 3.5 x 4 x 3.4 cm, showing intermediate T2, high T1 signal intensity, a complete signal drop on fat-saturation images, and no restricted diffusion, which indicated lipoma characteristics (Figure 1).

case_images: Intraoperatively, we discovered a pedunculated rectal mass spontaneously protruding beyond the anal verge at 12-3 o'clock (Figure 2A). In addition to being soft and yellow, the mass had a smooth surface and a fine texture (Figure 2B).
