Hypoechoic and anechoic areas of the liver are both described as findings on liver ultrasound. Hypoechoic areas of the liver may be associated with diseases such as hemangiomas and tumors, and anechoic areas may be associated with diseases such as cysts and abscesses. Normally liver ultrasound shows strong echoes. Liver hypoechoic area represents the density of the lesion area is lower than normal liver tissue, which may be caused by hemangioma, tumor and other diseases. Liver non-echoic area represents that the lesion tissue is fluid lesion, which may be cyst, abscess and other diseases, and the possibility of metastatic liver cancer cannot be ruled out. The results of hypoechoic and anechoic areas of the liver alone cannot determine the specific condition, and further examination of liver CT, magnetic resonance, pathological biopsy and other items are needed to find the cause.
