[|Human|] My son is 16 years old and has a lump on the side of his head that you can feel a pulse in. I took him to see his Dr. They were going to figure out what type of test to do, example US, and get back to me. What is your recommendations? What do you think it is?
[|AI|]  Welcome to Chat Doctor. 1. Pulsating lump suggest vascular lesion - which can be intro cranial extension, or extra cranial vascular malformation. 2. In this case initially as your doctor suggested USG soft tissue swelling is recommended.3. Ultrasound will evaluate the nature of the swelling (vascular / cystic / soft tissue) its source and extensions. 4. Depending on the findings further investigations are required. 5. In case of external lesion and non-vascular a small incision and Chat Doctor.  If internal extensions - MRI will be required. Good luck. Hope I have answered your query,anything to ask ?
