A 54-year-old woman presented to the emergency department complaining of abdominal pain. She reported a chronic inability to gain weight, fatigue, and loose stools, which were frequently blood-tinged. Physical examination showed she was remarkably thin; her vital signs were stable. Her abdomen was diffusely tender to palpation but without peritoneal signs. Hemoccult examination was positive. Laboratory tests revealed low hematocrit levels. Contrast-enhanced computed tomography (CT) of the abdomen and pelvis was performed (Figure 1). The patient was admitted to the hospital and underwent a small bowel follow-through the next day (Figure 2).
