DUCTAL CARCINOMA IN SITU-DCIS - radiologist

• Traditionally, carcinomas in situ represent a preinvasive form of the lesion with different histological types: intraductal lobular or papillary forms.
• 30-60% become invasive (within 10 years)
• In 2003, the World Health Organization (WHO) divided all proliferative intraductal lesions into several developmental types:

• • • -typical ductal hyperplasia (UDH)
    • -atypical ductal hyperplasia (ADH)
    • -ductal carcinoma in situ (DCIS)

DCIS

• low grade (G1)
• intermediate grade (G2)
• high grade (G3)

DCIS – mammography

• 90% are demonstrated by microcalcifications
• as broken architectonics
• SENSITIVITY OF MAMMOGRAPHY IS 56-95%

DCIS - ultrasound

• Only ultrasound devices with high-frequency probes can detect microcalcifications, which must subsequently be defined mammographically.

DCIS - MR mammography

• The detection of DCIS directly depends on the degree of differentiation of the lesion as well as on the experience of the radiologist.
