I had an us done and would like to know if anyone can tell me if it sounds serious: right lobe 4.7 x 1.9 x 1.4cm. Left lobe 5.2 x 1.9 x 1.4cm. On the right, a hypoechoic nodule 13 x 10 x 9mm, primarily solid with some central vascularity and microcalcifications. Left, 11x9x7mm nodule, hypoechoic and heterogeneous with central vascularity and small component of cystic change and scattered microcalcifications.
