case_images: USG revealed mild wall thickening in the region of the sigmoid colon with the presence of an intraluminal, curvilinear, hyperechoic arc-like surface casting a prominent posterior acoustic shadow [Figure 1].

case_images: Scanning with a linear high-frequency probe revealed the arc to be composed of multiple, tiny 4-8-mm-sized hyperechoic shadows [Figure 2].

case_images: Mild associated inflammatory changes were present with circumferential mural thickening (3-4 mm) and stranding of the pericolonic fat [Figure 3].
