case_images: An esophagogastroduodenoscopic (EGD) examination revealed a round mass of about 3-cm at the duodenal bulb, with normal surrounding mucosa and central ulceration (Figure 1).
case_images: Abdominal CT scan showing an exophytic well-defined round mass in the duodenal bulb. The mass enhanced as gastric mucosa and was presumed to be a duodenal gastrointestinal stromal tumor (GIST).
