Echogenic means something that is generating echoes.
In your liver
, there is this area which is more echogenic which means it is more whiter than the rest of liver.
An echogenic area if well defined, commonly is a hemangioms which is a benign lesion. Else it can be a fat containing lesion and less likely a problematic one.
I would suggest you to go for follow up ultrasound
after 3 months to see if there is any change in size.
Hope this helps.
