We experienced a small solid and cystic tumor 24 mm in diameter, which proved to be a hyperechoic mass on ultrasonography. Any small solid and cystic tumors do not reveal a proper ultrasonogram because of their histological structures. Given the resolution that can be expected from ultrasonic diagnostic equipment, it is reasonable to make a comparison with a low-magnified histological picture when characterizing the ultrasonogram. The low-magnified histological picture of this tumor revealed a sponge-like structure with scattered numerous small fissures in the solid tumor, we concluded that the hyperechoic pattern of this tumor was the result of its sponge-like histological structure.
