Figure legends
Figure 1A: CT. Gas and extensive abscess formation in the preperitoneal space from the lower abdomen to the pelvis.
Figure 1B: Laparoscopic image. There was marked swelling of the abdominal wall centered on the midline umbilical cord, suggesting abscess formation in the same area.
Figure 1C: CT. A slightly hyperdense cord-like structure extending from the umbilical region to the bladder, which was assumed to be a urachal remnant
Figure 1D: Laparoscopic image. The median cord, i.e., the presumed urachal remnant, was detached from the abdominal wall.
