            • Lobular or acinar calcifications (Ca⁺⁺)
          • Definitions

            • Round Ca⁺⁺: Smooth, spherical or ovoid Ca⁺⁺ ≥ 0.5 mm
              • When multiple, may vary in size
            • Punctate: Subset of round Ca⁺⁺; < 0.5 mm, round, smooth Ca⁺⁺
            • Group: Custer of ≥ 5 Ca⁺⁺ within span of 1 cm; when more numerous, may span to 2 cm
            • Regional distribution: Occupy large portion of parenchyma (> 2 cm span), not in ductal distribution
            • Linear distribution: In line; suggests deposits in duct
            • Segmental distribution: Cone with apex directed to nipple; suggests deposits in duct and its branches
