a–c Ultrasound images for two different patients presenting with an anterior abdominal wall postoperative fluctuant swellings. a, b Ultrasound and color Doppler images for a patient with a right iliac fossa swelling showing hypoechoic subcutaneous collection with double echogenic suture fragments inside (curved white arrow in a) and peripheral vascularity (marginal vascularity) is seen in b; this was operatively confirmed as a suture abscess. c An ultrasound image for another patient showing a large septated supraumbilical abdominal wall subcutaneous collection (between the white open arrows) that was present after a mesh placement for an epigastric hernia repair; this was operatively proven as a postoperative seroma, and a hernia recurrence was excluded
