Ductal Carcinoma in Situ
A 57-year-old patient presents for evaluation of right nipple discomfort. The patient has family history of a mother and sister with premenopausal breast cancer.
CLINICAL HISTORY
A 57-year-old patient presents for evaluation of right nipple discomfort. The patient has family history of a mother and sister with premenopausal breast cancer.
FINDINGS
Digital mammography shows area of calcifications (Figure 1a-b). Magnification views demonstrate intraductal pleomorphic microcalcifications in the right 11:00 area (Figure 1c).
No noted findings on physical exam or ultrasound.

(Figure 1c)
MRI imaging performed for extent of disease demonstrates linear beaded enhancement extending from nipple posteriorly for 8cm within the right breast upper outer quadrant (Figure 2a-b).

DIAGNOSIS
Vacuum assisted stereotactic needle core biopsy of the right breast 11:00 microcalcifications reveals ductal carcinoma in situ.
DISCUSSION
This case demonstrates the benefit of multimodality imaging including digital mammography and breast magnetic resonance imaging (MRI) in this patient, which led to a diagnosis of ductal carcinoma in situ (DCIS). There has been some conflicting information in the literature regarding MRI and its usefulness in the evaluation of DCIS. For this patient, the MRI revealed the extensive area of involvement more so than mammography. This information was critical to the surgeon for surgical planning.

Can Abbreviated MRI Have an Impact in Differentiating Intraductal Papilloma and Ductal Secretion?
June 3rd 2025For patients with inconclusive ultrasound results, abbreviated breast MRI offers comparable detection of intraductal papilloma as a full breast MRI protocol at significantly reduced times for scan acquisition and interpretation, according to a new study.
Can AI Assessment of PET Imaging Predict Treatment Outcomes for Patients with Lymphoma?
June 2nd 2025The use of adjunctive AI software with pre-treatment PET imaging demonstrated over a fourfold higher likelihood of predicting progression-free survival (PFS) in patients being treated for lymphoma, according to a new meta-analysis.
