👉Papillary lesions of the breast are common.
👉These highly vascular lesions are intraductal and may transform into malignant variants.
👉In benign papillary lesions, a vascular stalk may be demonstrated on color Doppler scanning while multiple feeding vessels may be seen when imaging malignant papillary lesions.
👉When papillary lesions infarct, the vascular stalk will not be demonstrated.
👉The ability to reliably distinguish papilloma, in-situ papillary carcinoma, and invasive papillary carcinoma is not possible with ultrasound and is quite challenging even on core biopsy.
👉Open surgical biopsy may need to be performed to distinguish malignant from benign papillary lesions.
👉An “acorn” cyst is lined with papillary apocrine metaplasia which can form a mural nodule.
👉The nodule in an acorn cyst is less echogenic than papillomas or papillary carcinomas, is usually concave, following the contour of the cyst (thus the appearance of a cap on an acorn) instead of convex, and does not have a vascular stalk.
👉The mural nodule caused by papillary apocrine metaplasia also would not extend into the duct as the papillary lesion shown in the image does.

👉Tubular adenomas and fibroadenomas have a similar sonographic appearance and are frequently round or oval, although tubular adenomas can be fusiform or spindle shaped.
👉Both lesions occur during reproductive years and would not commonly present as a new finding in a postmenopausal patient.
