Splenic abscess is an uncommon clinical condition which is usually treated with splenectomy with its attendant risks. Image-guided percutaneous drainage of splenic abscesses has been described in adults. The case of a 12-year-old boy with a splenic abscess who was successfully treated with ultrasound-guided percutaneous catheter drainage is presented. Image-guided percutaneous drainage in children can be a safe and effective alternative to surgery.
