How often do brain tumor headaches determine the localization and laterality of brain tumors?
Studies show that the location of the headache does not correlate well with the location of a brain tumor, especially for supratentorial brain tumors. Instead, these tumors often result in diffuse headaches that are unilateral in less than 50% of patients. When unilateral, however, brain tumor headaches are almost always on the same side as the tumor. Posterior fossa tumors are different, and they have strong association with occipital rather than frontal or temporal headaches.
