A 20-year-old otherwise healthy woman presented to the emergency department after a motor vehicle crash in which computed tomographic images of the abdomen were obtained as part of the trauma evaluation. Small free fluid within the pelvis and 2 large mesenteric masses were discovered adjacent to the liver, pancreas, and stomach (Figure 1). An endoscopic ultrasound-guided fine-needle aspiration of the abdominal mass was obtained and the diagnosis was made. The patient underwent exploratory laparotomy and en-bloc resection of the intraperitoneal tumors.
