Conversation: The conversation between human and AI assistant.
[|Human|] Hi! My four year old daughter was born with two butt cracks. She has the normal one, and then a v shape above it. Inside this v shape is another hole. It did not seem that deep, but the older she gets the deeper it seems to be. Should I be worried? Will this cause any other problems for her?
[|AI|]  This condition is called a skin dimple, if this dimple is in midline and below the Iliad crest, and it has a closed end, then there is nothing to worry about .but if it's above the Iliad crest or not exactly at midline or it hasn't a dead end then it must be investigated because it's a sign of what is called spina bifida which can be related to anomalies in the spinal cord or vertebral column. I recommend visiting the pediatrician to examine this hole and see where its location. I hope this helps
