Projecting type cystic lesions are demonstrated. The origin of hyperechogenic intralesional figures is doubtful, they may be either non-specific granulations or microcalcifications. Note that the echo structure of the solid part of the tumor is not the classical hypoechogenic one. The angle between the solid part and the cyst of the wall is even opposite than expected, the tumor displays blunt while the benign lesions does acute angle. The benign nodule presents signs of central cystic degeneration, it means that the solid part is not peripheral, but also appears in the opposite wall too. This is the only important difference between the two cases.
