[|Human|] my 3week old baby has a soft mass on right lower back... it is close to the spine and it almost feels fixed. it is about 4cm x 2cm, it appears to be slightly dis colored (bluish) but it is not painful to touch, the outer skin is not discolored... what can it be?
[|AI|]  Thanks for asking on Chat Doctor. Unfortunately the details provided by you are not enough. You have not indicated whether the swelling had been present since birth and whether it has progressed in size. There are some conditions like spina bifida, meningococci and meningomyelocoele etc. where there are deformities in the spine and the covering of the spinal cord protrudes through the gap of the vertebrae. Your baby could have such a condition. It is difficult to comment further without feeling it. Get in touch with your doctor and ask him. He would be able to feel it manually and also order an ultrasonogram if he feels required. It is difficult for me to comment further without examining it. Hope that answers your query. Feel free to revert in case of further queries if any.
