I'm very new to this site. My daughter is expecting twin boys. At her 18 week 5 day ultrasound the neonatal specialist found one very small hemangioma on one twin's liver. He said he sees a lot of these, and it isn't anything to be concerned about. Everything else looked perfect. I didn't ask many questions because I didn't want to worry my daughter, but now I'm reading scary things on the internet. I am so thankful I found this site. Is this really nothing to worry about, and what should we expect?
