Postoperative imaging modalities. a) Computed tomography (CT) 6 months after surgery. No abscess is seen. b-d) CT 1 year after surgery. A marginally enhanced low-density mass lesion is seen in the lower abdominal wall (b). The mass lesion is adjacent to the bladder wall with bladder wall thickness (c, yellow arrow) and the pubic bone with partial bone destruction (d, yellow arrow). The tumor shows high uptake on positron-emission tomography (e).
