What should sculptra PLLA injections look like on ultrasound of buttocks after 3 mo? My doc said he didn’t see any sign of foreign matter other than what he called post injection scarring. I think they are tiny nodules. I ask because sadly I questioned what was injected after the fact. Hence ultrasound. I expected to see tiny scattered particles not ONLY nodules. Could the PLLA have already dissolved after just 3 mo except nodules or are nodules what actually make PLLA discernible on ultrasound?
