What is complex hypoechoic?

Complex hypoechoic refers to a specific ultrasound finding where a lesion or area appears darker than the surrounding tissues due to its composition, which may include various structures like fluid, solid components, or tissue. This term often indicates that the area is not uniform and may suggest the presence of a more intricate pathology, such as an infection, tumor, or cyst with mixed characteristics. Further evaluation, including additional imaging or biopsy, may be necessary to determine the exact nature of the complex hypoechoic area.
