IMAGING OF DUCTAL CARCINOMA IN-SITU OF TH E BREAST

The incidence of ductal carcinoma in situ (DCIS) has increased with th e widespread use oi screening mammography. DCIS is often suspected whe n clustered microcalcifications are evidenced on routinely performed m ammography. High quality mammographies are required and should be comp leted with magnification views. Mammographic - pathologic correlations are described according to the new classifications as well as unusual forms of presentation on mammography. Early contrast enhancement in D CIS on dynamic MRI is reported and seems to be related with angiogenes is, A wire localization procedure of non-palpable lesions has to be pe rformed and per-operative specimen radiography is mandatory. Stereotax ic large core needle biopsy is a valuable alternative to surgical biop sy but a multidisciplinary team approach is necessary and follow-up is recommended if no excisional biopsy is done. Quality in the managemen t of DCIS depends on the coherence of the ''multidisciplinary team''.
