case_images: Radiological and pathological findings of immature gastric teratoma in a 3-month-old boy.. A. Longitudinal US of the abdomen shows a 20 x 13 x 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 x 9 x 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.

case_images: US revealed a large, mixed-echoic, solid and cystic mass in this same area (Fig. 1A), while unenhanced abdominal CT scans depicted a well-defined heterogeneous mass with intratumoral nodular calcifications (Fig. 1B) and a suspicious focal area of fat density. These scans also indicated that the solid portion of the mass was well enhanced (Fig. 1C). The gross specimen of the round exogastric mass thus obtained measured 14 x 9 x 6.5 cm and originated from the posteroinferior wall of the stomach along its greater curvature (Fig. 1D).
