Abstract
- Gastric teratomas are extremely rare neoplasms and almost exclusively benign. They occur predominantly in males and generally present as a palpable abdominal mass. To our knowledge, only one adult case has been described in the Korean literature. We report a case in which an immature gastric teratoma in a 3-month-old boy was revealed by CT and US.

Fig. 1 Radiological and pathological findings of immature gastric teratoma in a 3-month-old boy. A. Longitudinal US of the abdomen shows a 20 × 13 × 9 cm-sized mixed-echoic mass in the left upper abdomen, with multifocal cystic components (arrows). B. Unenhanced abdominal CT at the level of the kidneys shows a well-defined heterogeneous mass displacing the left kidney posteriorly and the bowel loops medially (arrows). Note the presence of multiple nodular calcifications in the mass (arrowheads). C. Enhanced abdominal CT at the level of the stomach shows a large exogastric, solid, cystic mass arising from the greater curvature of the stomach, and continuous with a protruding intraluminal polypoid mass (arrows). Note the well-enhanced gastric wall (arrowheads) and the presence of air bubbles in the gastric lumen (small slender arrow). D. Gross specimen of the round exogastric mass, 14 × 9 × 6.5 cm in size, which originated from the posteroinferior wall of the stomach along its greater curvature (arrows). Cut section of the tumor shows some cystic areas filled with serous and mucous material, and keratin, and the presence of hemorrhagic foci.
