Introduction

Infection-associated headache, tension-type headache and migraine are the most prevalent headaches in the general population as well as in women. However, any new-onset headache occurring in a patient ‘at risk’ (on anticoagulant treatment, with a previous history of malignancy, etc) mandates prompt evaluation to exclude a serious underlying condition. Similarly, when headaches first present during pregnancy or post partum, a diagnostic evaluation is indicated even tough primary headaches are most common.1
