We describe an iatrogenic perforation of a paraclinoid aneurysm during balloon-assisted coil embolization that resulted in simultaneous subarachnoid contrast extravasation and a carotid cavernous fistula. The causative factors specifically related to the balloon-assisted method that led to aneurysm rupture are discussed as well as strategies for dealing with this complication.

Infantile dural sinus fistulas are rare and generally have a poor prognosis unless treatment can be undertaken. We report a unique case of an infantile dural sinus fistula with secondary pial recruitment that was managed conservatively. Subsequent spontaneous regression of the lesion occurred over 11 months. The clinical and angiographic features that indicated a probable favorable prognosis ar...

A rare case of widespread fibromuscular dysplasia (F.M.D.) is reported, involving the cervico-cephalic arteries associated with multiple dissections, saccular aneurysms and a carotid-cavernous fistula. A detailed post-mortem examination revealed FMD involvement of the intracranial vessels, not demonstrated by arteriography.

A 40-year-old woman was admitted to a local hospital following the acute onset of severe right temporal and retroorbital headache associated with nausea and vomiting. For 2 or 3 days before the onset of symptoms she had experienced a flulike illness with repeated episodes of coughing. She also had a mild temperature elevation. Her past medical history was unremarkable. At the time of initial ex...

A single-hole arteriovenous fistula (A VF) consists of a solitary abnormal communication between an artery and a vein without an intervening capillary network. An AVF must be distinguished from an arteriovenous malformation (A VM), which is composed of a complex network of arteriovenous connections (nidus or core). Most AVFs develop as a result of trauma; those between the internal carotid arte...

PURPOSE To assess serial dynamic enhanced computed tomography (serial DE-CT) as a diagnostic tool for carotid-cavernous sinus fistula (CCF). METHODS Serial DE-CT was performed in seven patients (ages 31-74) with CCF. Contrast material was injected intravenously at a dose of 60 mL with an injection speed of 4 mL per second. Serial axial images of the cavernous sinus were undertaken every 3 sec...
