Abstract

Giant arachnoid granulations have been reported to be associated with headaches, which can be acute or chronic in presentation. In some cases, idiopathic intracranial hypertension, previously called pseudotumor cerebri, may occur. The pathophysiology of these enlarged structures seen as filling defects on imaging is not clearly defined, although they are presumed to cause symptoms such as headache via pressure resulting from secondary venous sinus obstruction. We present a unique presentation of secondary headache in a 39-year-old man with no prior history of headaches found to have giant arachnoid granulations, presenting as migraine with aura.
