Surgical strategy in abnormally increased Fluorine-18 fluorodeoxyglucose uptake in an asymptomatic lower esophageal submucosal tumor – Report of a case

Abstract

INTRODUCTIONLeiomyoma is the most common benign tumor of the esophagus (67–80%), it represents 0.4–1% of all esophageal tumors.PRESENTATION OF CASEAn incidentally discovered gastro-esophageal submucosal tumor was found to have increased fluorine-18-fluorodeoxyglucose (FDG) uptake on positron emission computed tomography (PET/CT). After laparoscopic surgical exploration and local enucleation the tumor turned out to be a benign esophageal leiomyoma.DISCUSSIONThere are few reports of esophageal leiomyomas with a positive uptake on (PET/CT) and even fewer adopting our combination of a minimally invasive approach and frozen section examination as a management plan. Our approach avoided excessive morbid surgical resections and underestimation of a malignant disease.CONCLUSIONWe report this case hoping to expand the existing literature on the topic and to highlight the limitations of PET/CT in guiding the diagnosis and subsequently the management of esophageal submucosal tumors.
