Epidemiology
Peak age of presentation is about 50 to 60 years.
Clinical presentation
Large palpable, immobile mass.
Radiographic features
Mammogram
- spiculated hyperdense lesion
- oval/lobulated lesion
- microcalcifications
Ultrasound
- ill-defined lesion
- hypoechoic mass
- hyperechoic angular margins
- posterior acoustic shadowing
- ductal extension may be seen which is extension of the lesion into surrounding parenchyma
- branched or spiculated pattern
- microcalcifications
MRI
-
T1
- isointense to parenchyma
- hypointense to fat
-
T1 C+ (Gd)
- ring enhacement with centripetal progression
- dilated veins draining the tumor
-
T2
- iso to hypointense to parenchyma
- hyperintense edematous zone
