What does hypoechoic lesion in liver mean?
A hypoechoic mass may be a tumor or abnormal growth. It may be benign or malignant. A benign tumor may grow but it will not spread (metastasize) to other organs. A malignant (cancerous) tumor can spread and invade other parts of the body.
What is avascular hypoechoic?
An avascular hypoechoic testicular lesion was defined as one with echogenicity lower than that of adjacent testicular parenchyma and without internal vascularity during color Doppler imaging.
What does liver hyperechoic mean?
For example, a fatty liver (steatosis) is typically brighter (more “echogenic” or “hyperechoic”) on a liver ultrasound than normal liver, while hepatitis may be less bright (“hypoechoic”). A cirrhotic liver often looks shrunken and lumpy.
How big are hypoechoic focal liver lesions in humans?
Methods: We studied 88 hypoechoic liver lesions (diameter range, 1-18 cm; with 18 lesions 2 cm or less) found on conventional grayscale sonography (US) with contrast-enhanced ultrasonography (CEUS).
Are there any benign or malignant intratesticular lesions?
Benign intratesticular lesions are rare, but recognition is important to avoid unnecessary surgical intervention. The ultrasonographic (US) features that help differentiate benign from malignant intratesticular lesions are emphasized by the authors.
How many avascular hypoechoic testicular lesions are malignant?
Although most (63.5%) avascular hypoechoic testicular lesions are benign, a substantial proportion (36.5%) are malignant. In this study, the data showed that patients with malignant lesions more often were younger and had elevated serum tumor markers and testicular atrophy.
How big are the liver lesions on CEUs?
The enhancement pattern of 13 small (< or = 2 cm in diameter) hypervascular liver lesions (3 capillary hemangiomas, 2 FNHs, 4 HCCs, 4 metastatic endocrine tumors) was better demonstrated on CEUS than on helical CT. In these cases the hyper vascularization of the lesions shown on CEUS was not confirmed on CT.
