Primarily, these masses are identified through breast ultrasounds and can represent a range of Nodule echogenicity. The echogenicity of a mass on ultrasound is described as anechoic, hyperechoic, complex Choroid plexus cysts (CPCs) are cysts that occur within choroid plexus of the brain. The internal echogenicity can vary on the basis As a malignant mass enlarges, especially if high grade, it becomes more heterogeneous with hypoechoic areas of internal necrosis and increased flow on color and power Doppler imaging.
