sclerotic lesion but no head trauma

[mepo1945]

I have a question and maybe someone else has experienced this.
I am following up soon with a neurologist.

I went to the ER with a severe headache that woke me up out of a deep sleep, it was like a headache I had never had before and it was all over my head. Two weeks prior to this I had a very local sharp headache on the top left side of my head and since I thought I had a sinus infection that is what I was treated for and was told that the headache would go away with the antibiotics. It took about a week for that headache to go away.
The one I currently had and still have that I went to the ER for resulted in a CAT scan that showed no bleeding or intracranial mass and the doctor said the meningis appeard fine. However, there was a sclerotic lesion on the right frontal skull. since I have never had any head trauma and the lesion did not form along the places where as an infant your skull comes together they want me to follow up. My question is, what can cause these sclerotic lesions and should I be concerned, especially since my headache has not gone away?

Thanks!

I'm happy that you are being followed up for this. A local lesion in the skull bone is often an insignificant, incidental finding, such as a small osteoma, which rarely causes symptoms, it seems unlikely that it's related to your headaches, however it's necessary that you get your own neurologist's opinion about this since some bone lesions require closer attention especially if they change with time. A sudden, severe headache always needs to be thoroughly evaluated.
