Excisional biopsy (no contrast).

Imaging recommendation · Breast

Mucocele-like lesion on imaging or core biopsy

Recommended: Diagnostic Mammogram + Targeted US + Stereotactic biopsy is the preferred imaging study for mucocele-like lesion on imaging or core biopsy. Mucin-containing dilated ducts.

Recommended study

Diagnostic Mammogram + Targeted US + Stereotactic biopsy

MG No contrast Preferred Breast Outpatient Reviewed 2026-05

Mucin-containing dilated ducts. Spectrum from benign (mucocele-like lesion) to in situ / invasive mucinous carcinoma.

If the default doesn't apply

Surgical excision after core biopsy

Excisional biopsy No contrast

Watch-outs

Upgrade rate to malignancy

Higher upgrade rate than fat necrosis or simple cysts — excise after core biopsy in most centers.

Pearls

Clustered punctate / amorphous calcifications.
Mucinous carcinoma is associated entity — surgical management often needed.
Pathology will distinguish benign mucocele-like from invasive mucinous carcinoma.
