Intranodular hyperechogenic figures - case 2174 (ultrasonographic picture 2b)

Right lobe, longitudinal view, enlargement. Some of the echogenic granules are located dorsal to more hypoechoic areas (white arrows), which raises the possibility of back wall cystic enhancement as a cause of these figures. At least one of the granules has a dorsal tail (yellow arrow). On the other hand, the punctate echogenic focus (marked with a red arrow) fulfills the criteria of microcalcification.
