A 23-year-old woman had a progressively enlarging mass associated with abdominal distention and a dragging type of discomfort for 1 week. She denied any history of hematemesis or hematochezia. On abdominal examination, an irregular mass measuring 20 × 10 cm without tenderness was found, and no bruit was heard on auscultation. No other vascular anomalies were detected on systemic examination. All laboratory test results were within normal limits. Upper gastrointestinal endoscopy showed normal gastric mucosa. Nonenhanced computed tomography of the abdomen showed a partially well-circumscribed, mixed cystic and solitary mass that partially enveloped the stomach and compressed adjacent organs, likely arising from the stomach (Figure 1).
