What is an irregular hypoechoic?

An irregular hypoechoic lesion refers to an area on an ultrasound that appears darker than the surrounding tissue, indicating that it reflects fewer ultrasound waves. This characteristic often suggests the presence of a pathological process, such as a tumor or cyst, which may not have well-defined borders. The irregularity in shape can raise concerns for malignancy or other significant conditions, necessitating further evaluation or diagnostic imaging to determine the nature of the lesion.
