What is the interpretation of ultrasound of the axillary lymph node?

Hello,

Welcome to icliniq.com.

I thoroughly read your query and understand your concern.

Your ultrasound report says that there is an echogenic ovoid structure in the right axilla corresponding to a similar structure seen in your previous ultrasound that now measures 2.0 x 4.7x 1.1 cm. It contains some internal vascularity which means few abnormal blood vessels are seen in it. This structure could represent a mildly enlarging or persistent right axillary lymph node. It says mildly enlarging because its size in the previous ultrasound was slightly less persistent because this structure is still seen in the present ultrasound.

No normal-appearing fatty hilum was identified. Normal lymph nodes have a central fatty tissue which is called the fatty hilum, that is visible on ultrasound. This hilum is lost in pathologies of lymph nodes and is then not seen while scanning. The report goes on to say that further evaluation or continued follow-up is suggested. Further evaluation is usually done by biopsy of the node or mass in case it has not been done already. Follow-up is by ultrasound or CT (computed tomography) at six months or yearly intervals, depending on the physician's discretion, to evaluate if the disease is progressing or regressing.

I hope this helps.

Kind regards.

Hi,

Welcome back to icliniq.com.

I understand your concern.

It is difficult to say with complete certainty based on just imaging whether a node is benign or malignant, though a few features help in characterizing a node to be malignant such as irregular margins, internal vascularity, taller than wider lesion, round shape, loss of fatty hilum, infiltration into surrounding areas, etc. This can be discussed with the radiologist who has access to your images. Usually, follow-up is recommended for suspicious lesions to look for an increase in the size of the lesion, change in shape, increased irregularity, increased vascularity, spread to other organs, etc. A definite diagnosis can only be reached with a biopsy of the lesion. Though in your case, the size shows only a slight increase from the previous scan and some internal vascularity, I suggest you follow it up after discussing it with your physician.

Hope this helps.

Kind regards.
