Positron emission tomography (PET) (a) and transverse-section positron emission tomography-computed tomography (PET-CT) (b) scans: showing hypermetabolic fluorodeoxyglucose- (FDG-) avid mass lesion in gastric fundus and extending into gastric cardia and lower gastroesophageal junction. In addition, it was associated with a few hypermetabolic FDG-avid lesions in the gastrohepatic junction, indicating lymph node metastases. No evidence of distant metastasis was identified.
