A Teenager With Acute Abdominal Mass: A Case of Gastro-Gastric Intussusception

Abstract

A previously healthy 17-year-old boy presented to the emergency department with worsening left upper quadrant abdominal pain, a history of nonbloody, nonbilious emesis for 2 days, more recent bloody emesis for 1 day, and an abdominal “mass.” He had eaten dinner as usual 3 days earlier and gone to sleep. He woke up that morning with abdominal pain and felt a “mass” in the left side of his upper abdomen, which he stated would decrease in size by applying pressure. He started vomiting the same day, which initially contained food contents and exacerbated his pain.
