A 51-year-old male experienced wound dehiscence with culture-proven Staphylococcus aureus infection following Rives-Stoppa repair of a ventral incisional hernia. Ultrasound (a) showed an ill-defined, inhomogeneously hypoechoic region (caliper) at the surgical site, without fluid portions amenable to aspiration. Corresponding post-contrast axial (b) and sagittal (c) CT images showed a band-shaped abscess (*) of the anterior abdominal wall with enhancing periphery (arrows), interposed between the PM and rectus muscles, which drained externally through a fistula (thick arrows in c) (note hyperattenuating plug at skin orifice)
