Cervical extramedullary mass lesion due to chronic CSF overshunting: case report and literature review.

Introduction: Several emerging clinical and neuroimaging conditions due to CSF intracranial hypotension have been documented.

Patients with this type of cervical myelopathy usually evolve with marked clinical manifestations of spinal cord involvement.

Carotid-cavernous sinus fistulae are anomalous communications between the carotid artery and the cavernous sinus. They are classified according to whether they are traumatic or spontaneous, but distinction in relation to the anatomical origin of the branches of the carotid artery which supplies them is more important.

Moya-Moya disease is an obstruction of the internal carotids and of the afferent and efferent channels of Willis's polygon, which causes a collateral circulation, responsible for the typical angiographic image of a "puff of smoke" (Moya-Moya, in Japanese). Its etiology is unknown, and it might be congenital or acquired. It has been associated with congenital diseases such as Neurofibromatosis and disease of the falciform cells, among others.
