In contrast, tissues with lower echogenicity are called "hypoechoic" and are usually represented with darker colors. Areas that lack echogenicity are called "anechoic" and are usually displayed as completely dark. [1]
Hypoechoic – less echogenic (darker) than normal; Isoechoic – the same echogenicity as another tissue; Transvaginal ultrasonography – Ultrasound is performed through the vagina; Transabdominal ultrasonography – Ultrasound is performed across the abdominal wall or through the abdominal cavity
Between the pyramids are the cortical infoldings, called columns of Bertin (Figure 1). In the pediatric patient, it is easier to differentiate the hypoechoic medullar pyramids from the more echogenic peripheral zone of the cortex in the parenchyma rim, as well as the columns of Bertin (Figure 2).

CEUS examination shows central tumor filling of the circulatory bed during arterial phase and completely enhancement during portal venous phase. During this phase the center of the lesion becomes hypoechoic, enhancing the tumor scar. During the late phase the tumor remains isoechoic to the liver, which strengthens the diagnosis of benign lesion.
A hyperechoic lesion with surrounding vascularity is seen in the groove between the testis and epididymis. [citation needed] At sonography, the appendix testis usually appears as a 5 mm ovoid structure located in the groove between the testis and the epididymis. Normally it is isoechoic to the testis but at times it may be cystic.
Suspicious findings in a nodule are hypoechoic, ill-defined margins, absence of peripheral halo or irregular margin, fine, punctate microcalcifications, presence of solid nodule, high levels of irregular blood flow within the nodule [11] or "taller-than-wide sign" (anterior-posterior diameter is greater than transverse diameter of a nodule).
