An incidental discovery of an accumulation of F-fluorodeoxyglucose (FDG) in the oral cavity of patients with malignant tumours on FDG positron emission tomography (PET) can pose a problem regarding the differential diagnosis of metastatic lesions. Large accumulations can often be found even when tumours in the salivary or thyroid gland are benign, so FDG-PET is limited in its ability to differentiate between benign and malignant disease. This report describes a rare case of sialadenoma papilliferum in the buccal mucosa that was discovered incidentally on FDG-PET in a patient with multiple metastases to bone after an operation for rectal cancer.
在氟脱氧葡萄糖(FDG)正电子发射断层扫描(PET)检查中,恶性肿瘤患者口腔内意外发现FDG聚集,这可能给转移性病变的鉴别诊断带来问题。即使唾液腺或甲状腺的肿瘤是良性的,也常常能发现大量聚集,因此FDG-PET在区分良性和恶性疾病方面能力有限。本报告描述了1例颊黏膜乳头状涎腺瘤的罕见病例,该病例是在1例直肠癌术后发生骨多发转移的患者进行FDG-PET检查时意外发现的。
