Neurovascular headache and occipital neuralgia secondary to bleeding of bulbocervical cavernoma.

It has recently been suggested that the trigeminocervical complex plays a crucial role in the pathophysiology of neck discomfort that accompanies migraine attacks. Clinical and neurophysiological data have shown that pain within the occipital area may be transmitted by the first trigeminal branch, which supports an anatomical and functional link between cervical and trigeminal modulation of peripheral afferents. We describe a patient with an acute symptomatic migraine attack and chronic occipital neuralgia, both due to bleeding of a bulbocervical cavernoma. The clinical presentation is also discussed and related to recent scientific data on the role of the trigeminocervical complex in both the clinical picture and underlying pathophysiological mechanisms of cervical and head pain.
