Patient had undergone cardiac transplantation about 3 years prior. Upon coming to the ED this occasion it was for a three-day history of right lower quadrant pain. The white blood cell count was elevated, and a small-bowel X-ray examination showed some dilated small bowel loops but no free air. He was admitted, and an abdominal gastrointestinal ultrasound showed a mass measuring about 5 by 5 by 4 centimeters, which was presumed to be an appendiceal cyst. He underwent an ultrasound-directed percutaneous right lower quadrant aspiration; only a few drops of material were collected for diagnostic examination.

He was discharged on antibiotics and was to return in a few weeks for an interval appendectomy. ICD-10-CM: ICD-10-PCS: Rationale:
