title: Gastric Schwannoma mimicking malignant gastrointestinal stromal tumor and misdiagnosed by (18)F-FDG PET/CT.
abstract: Gastric Schwannoma is a rare benign mesenchymal tumor that accounts for only 0.2% of all gastric tumors. The current study presents a case of gastric Schwannoma misdiagnosed as malignant gastrointestinal stromal tumor (GIST) by esophagogastroduodenoscopy, endoscopic ultrasonography, and contrast-enhanced or not enhanced and (18)F-FDG PET/CT imaging.
