Abstract
Positron-emission tomography scans (PET) with fluorine-18-fluorodeoxyglucose ((18)F- FDG) are usually negative in leiomyomas. Two patients underwent a PET that showed an increased (18)F- FDG uptake of the distal oesophagus suggestive for malignancy. Both patients were operated on and histologic examination revealed a benign leiomyoma in both cases. We conclude that oesophageal leiomyomas are a potential cause of a false-positive PET. A high level of caution is needed in these diagnostically challenging cases to prevent unnecessary surgical procedures.
摘要
氟-18-氟脱氧葡萄糖（(18)F-FDG）正电子发射断层扫描（PET）通常在平滑肌瘤中呈阴性。两名患者接受的PET扫描显示食管远端(18)F-FDG摄取增加，提示为恶性肿瘤。两名患者均接受了手术，组织学检查显示两例均为良性平滑肌瘤。我们得出结论，食管平滑肌瘤是PET假阳性的潜在原因。在这些诊断具有挑战性的病例中需要高度谨慎，以避免不必要的手术。
