"Focal discontinuity or “step‑off” in the posterior rectus sheath is seen in transverse and longitudinal planes, often near the mid‑lateral aspect of the rectus. In dynamic evaluation, Valsalva or standing may increase the size/protrusion 5."

Additionally, CT is the modality of choice for complication evaluation, including bowel obstruction, wall thickening, poor enhancement, or mesenteric congestion, which suggests incarceration/strangulation 5."
