3D MIP (a) and axial fused PET/CT images (b and c) for a 67-year-old male patient with history of surgically resected gastric adenocarcinoma and splenectomy. No FDG-avid lesions at gastroesophageal anastomotic site, while splenectomy operative bed shows a localized collection with marginal increase of FDG activity and air loculi within (arrow), low-grade mediastinal lymph nodes as well as bilateral moderate pleural effusion and mild pelvic ascites demonstrating low-grade FDG activity. Final diagnosis confirmed by histopathology and radiological follow-up for splenectomy bed collection complicated with infection (an example of false-positive case)
