Fig. 6From: Role of diffusion-weighted magnetic resonance imaging in assessment of mammographically detected asymmetric densitiesA 68-year-old female patient with right mastalgia. Mammography craniocaudal (a) and mediolateral oblique (b) views show focal asymmetry in the right upper quadrant. This is associated with suspicious amorphous microcalcifications (BIRADS IV lesion). Axial STIR (c) image shows an ill-defined hyperintense segmental area seen in the right upper outer quadrant with dilated ducts. Axial TI contrast-enhanced fat-suppressed image on dynamic sequence (d) shows heterogeneous segmental non-mass enhancement with linear ductal extension towards the nipple. Dynamic time-intensity curve shows type II plateau curve (not shown). The lesion shows hyperintense signal in DWI at b value = 400 (e) denoting restricted diffusion, and low signal on ADC map (f) with measured ADC value 1.22 × 10–3 mm2/s. MRI findings: BIRADS IV lesion. Histopathological diagnosis: usual ductal hyperplasiaBack to article page
