回复：这个 4 mm 的东西很有可能是血管的分流 （a small vascular shunt ）或者

Thank you very much, Dr. Li.

A follow-up question, although it mentioned the chance for it to be cancer is small, but it still have a possibility. I heard that a hemangioma usually exist when one was born. However the CT-scan of four years ago did not find it. So I am still worried. Is that ture that the hemangioma will not appear later in someone's fouties?
