Intracranial aneurysm and arachnoid cyst: just a coincidence? A case report.

Context: Presence of an arachnoid cyst and a non-ruptured intracystic brain aneurysm is extremely rare. The aim of this paper was to describe a case of a patient with an arachnoid cyst and a non-ruptured aneurysm inside it. Clinical, surgical and radiological data were analyzed and the literature was reviewed.

Advances in the endovascular treatment of direct carotid-cavernous fistulas.

Carotid cavernous fistulas (CCFs) are abnormal connections between the carotid artery and the cavernous sinus. They are considered direct when there is a direct connection between the internal carotid artery and the cavernous sinus. These cases are generally traumatic.

Spontaneous acute subdural hematoma: A rare presentation of a dural intracranial fistula.

Dural arteriovenous fistulas are acquired lesions between the meningeal arteries and their associated draining veins. They may have highly variable clinical presentations and evolution, from severe neurological deficit to no or trivial symptoms. Intracranial hemorrhage occurs in less than 24% of all dural fistulas, and the bleeding is usually subarachnoid, more infrequently intracerebral, and rarely in the subdural space.
