title: A Case of Intraductal Papilloma of the Breast With High 18F-FDG Uptake on PET/CT.
abstract: We present a case of intraductal papilloma in the right breast of a 51-year-old woman with high F-FDG uptake. Its maximum standardized uptake value increased from 10.2 on early (1 h) PET/CT scan to 12.2 on delayed (2 h) PET/CT scan suggesting a primary breast cancer. However, histopathology proved it to be an intraductal papilloma. Immunohistochemically, strong expression of glucose transporter-1 and weak expression of hexokinase-II were noted in the papilloma. With the detection of a subareolar intracystic mass with high F-FDG uptake, intraductal papilloma should be included in the differential diagnosis.
