Eight patients (44%) underwent surgery. Four of 8 patients (50%) had benign tumors, 2 (25%) had infectious disease and 1 patient each had metastatic disease from a melanoma and a non-Hodgkin’s lymphoma.Conclusion: F-18 FDG PET-positive parotid incidentaloma is rare. The prevalence of a PETpositive parotid incidentaloma in our study was 0.3%. Clear-cut focal high-grade abnormal F-18 FDG uptake was seen in benign tumors, infectious and metastatic disease.Keywords: F-18 FDG PET-CT scanning, incidentaloma, parotid gland, prevalence http://www.dovepress.com/f-18-fluorodeoxyglucose-fdg-positron-emission-tomography-pet-positive--a2828 |
