What Does The Following CT Scan And Nasal Scan Report Indicate?

Hello Doctor, I have suffered from headaches for many years, recently of which occur daily and may start at any time of the day, or night (wake up during the night with a bad headache or first thing in the morning). i am 27 years of age, female. Recent CT scans displaysthe following: BRAIN SCAN moderate prominence bilateral superior extra-axial CSF spaces underlying the frontal and parietal lobes, more than would be expected for a patient of this age . NASAL SCAN CT Evidence of mild predominatly left maxillary and middlethmoidal chronic sinusitis. No CT evidence of focal mass or chronic fungal sinus infection. Suggestion of possible enchondroma 1.9cm left sphenoid body . Could any of these above be a possible cause for daily headaches, mainly occuring at the top part of my head (above my forehead when the hairline starts). Thank you
