Imagerie des céphalées

Headaches have a very high prevalence in western populations and various etiologies have been recently classified by the International Headache Society. Primary headache, without detectable organic substratum, in particular with imaging modalities, is distinguished from symptomatic headache secondary to neurologic or non-neurologic diseases. Rare secondary headaches require emergency imaging work-up and treatment due to the risk of hemorrhage, unruptured aneurysm, arterial cervical dissection and venous thrombosis.
