Previous picture Back to Case Next picture

Right lobe, longitudinal scan

Left lobe, transverse scan. A large cystic nodule occupies the lobe. The lesion has halo and presents intranodular hyperechogenic figures, great proportion of them is caused by back wall posterior enhancement. The brightest one in the medial part of the nodule might cause differential diagnostic problem. It fully corresponds to a microcalcification. However, in a cystic lesion such figure is more probably caused also by back wall cystic enhancement.
