Hi, my brother's son is 3 weeks old and yesterday we noticed a lump on his neck. We took him to the doctors today and did an ultrasound and we still dont know if it is from the muscle or the veins. We will do another and detailed ultrasound tomorrow. what could it possibly be? and what is the difference if it was a muscle or vein lump?

What Causes Lump On Neck Of A 3 Weeks Old ?
hi. which part of his neck is affected? does the lump go with fever and are there signs of infection? there are varied possibilities. but with his age, it could be a cystic hygroma, hemangioma, an arteriovenous malformation, a lipoma.. it is best if you consult with a pediatric surgeon.
