Figure 4 Preoperative evaluations (Case 2)(A) Gastroscopy revealed a huge ulceroinfiltrative mass in the gastric cardia. (B, C) Contrast-enhanced CT showed a 9.0×7.4×4.6 cm gastric tumor invading the pancreatic tail, without evidence of distant metastasis. Brown arrow: gastric cardia tumor extending to the gastroesophageal junction. Yellow arrow: suspected direct invasion of the pancreas by the gastric tumor. (D) PET imaging demonstrated a hypermetabolic mass in the stomach without distant metastasis (green arrow), shown in a right-rotated view from the left side to minimize overlap with physiological cardiac uptake.
