My 14 year old daughter had a small lump on the base of her skull a year ago.  Now it is the size of a quarter and when I touch it she gets a fever.  She has had a headache now for the past 2 days with a slight fever and feels like she is going to get sick.  And earlier today she felt off balance.  Is the lump on the back of her skull causing all these other symptoms?  What could the lump be?
Hi, dairy have gone through your question. I can understand your concern.  She may have Desmond cyst, some soft tissue tumor like lipoma or neurofibroma or some skin adnexal tumor. She should go for biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
