[|Human|] Hello, I was just googling lump on top of head and this site came up... I have a painless lump on the top of my head, and it feels like it is under the skull. It s in the center, and it s about an inch in diameter. Also, there is an indentation, about the size of a nickle, in front of it, directly where the fontanel would be, and another directly behind it. All three areas are perfectly aligned with the center of my skull. I m 43, female, about 175lb, and about 5 7 . I m perfectly healthy, and have been a very well-balanced vegetarian for over twenty years. Thanks so much. :)
[|AI|]  HI, Luke,Dear, Thanks for the query to Chat Doctor.1-I have studied your query in depth.2-DEar,IN my opinion, the lump of 1 inch on top of your head, painless,with nickel size front indentation and one indentation on back of the head lump-all aligned with the center of your skull, is of multiple cysts? Most probably-sebaceous cysts, 3 in no. in central line of your skull. And or/ it may be a Desmond cyst-with skull defects. This diagnostic puzzle would be clear on USG and Skull X-ray/CT and SSRI- of the head.3-Treatments-would be decided by a Surgeon-for sebaceous cyst or a Brain Surgeon-for Desmond /teratoid-cysts(congenital origin)-depending on the defects in the skull -if found.4-Hope this would solve your query to your satisfaction.5-Wellcome for more queries to me On Chat Doctor.6-Thnks once again for your inquisitive query. Have a Good Day.!!
