Core Tip

Core tip: Gastric mucormycosis is very rare, and there have been no reports on the F-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) finding of gastric mucormycosis. Since, endoscopic findings of gastric mucormycosis reveal ulcer margin with inflammatory/necrotic debris and hemorrhagic clots, F-18 FDG PET/CT of gastric mucormycosis reveal increased FDG uptake in the infected site. Additionally, reactive enlarged hypermetabolic lymph nodes in the perigastric chain could be observed. In this regard, it was difficult to differentiate gastric mucormycosis and gastric cancer by endoscopic findings and radiologic examinations. Therefore, careful consideration of clinical manifestations and precise diagnosis are necessary for optimal treatment of gastric mucormycosis.
