Differentiation of discrete lesions - case 1741 (ultrasonographic picture 5)

doi: 10.24390/thyrocase1741.05

Left lobe, horizontal view. This hypoechogenic-cystic area was described as a suspicious nodule on the previous ultrasound report. Note that in contrast with a nodule in pathological sense this lesion is not regular geometrical and there are many other similar, smaller areas in the thyroid. The intralesional hyperechogenic figures were misinterpreted as microcalcifications; these are in fact figures caused by back wall cystic enhancement.
