A hypoechoic lesion is an abnormal area that can be seen during an ultrasound examination because it is darker than the surrounding tissue. Such abnormalities can develop anywhere in the body and do not necessarily indicate cancer. Blood tests, biopsies, and further radiological studies may be required to determine the composition of a hypoechoic lesion, sometimes referred to simply as a lesion.

Detecting a Hypoechoic Lesion

During an ultrasound examination, a technician applies a handheld device known as a transducer to the area of the body requiring assessment. The transducer emits high frequency sound waves that are reflected back toward the device when they contact internal structures. A black and white image forms on a monitor, based on the intensity of the echoes. Radiologists call brighter images from highly reflective surfaces hyperechoic while areas that are less reflective appear as darkened regions and are said to be hypoechoic.

Hypoechoic lesions can occur in any part of the body and for a range of reasons. By looking at an ultrasound image, a specialist may be able to determine whether a lesion is a cyst or tumor, and if it is solid in nature or contains any fluid. The general appearance of a lesion does not necessarily indicate whether the area is benign or malignant, however.

I am hoping this is not what my sister has. She has been complaining lately of pain in her abdomen, of feeling full of gas, and of having pain when she goes to the bathroom. I wonder if the doctors might be able to find something by searching for these lesions on her kidneys. It would be such a relief if they could find something using this method. I will be looking into this to find out if there are free procedures offered to those with little or no health coverage.

Wait, I'm confused, is the *goiter* the lesion? Or does the lesion exist *inside* the goiter?

This is interesting, I had an uncle who thought he might have had one of these, but it turns out he was mistaken. We were all relived about that for sure!
