Hello, That cerebellar calcification is not related to your headache. It may be a remnant of an old lesion like an infection. Not the cause of the headaches. The mastoiditis, on the other hand, may justify your headache, such an infection of the mastoid bone which is located behind the ear may cause a headache on that side. For that reason, you should consult an ear specialist to check your ear and decide whether antibiotics are necessary. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Olsi Taka
