Intraductal papilloma (IDP) is a benign tumor of the breast. However, IDP has been reported to show high uptake of 18F-FDG using whole-body PET. We experienced IDP with low-grade ductal carcinoma in situ using dedicated breast PET, which is more sensitive than whole-body PET. The 18F-FDG uptake of the whole tumor was high, and differentiation between the carcinoma and the residual benign lesion was difficult. This is the first report of IDP detected with dedicated breast PET. Diagnosis of IDP is sometimes controversial; papilloma may show glucose uptake similar to that of low-grade carcinoma.
导管内乳头状瘤（IDP）是一种乳腺良性肿瘤。然而，据报道，全身 PET 显示 IDP 对 18F-FDG 摄取较高。我们使用专用乳腺 PET 检查到了 IDP 伴低级别导管原位癌，其比全身 PET 更敏感。整个肿瘤的 18F-FDG 摄取较高，且癌与残留良性病变之间的区分较困难。这是首次使用专用乳腺 PET 检查到 IDP 的报告。IDP 的诊断有时存在争议；乳头状瘤可能表现出与低级别癌相似的葡萄糖摄取。
