This study was designed to elucidate the generating mechanism, diagnosis and treatment of traumatic carotid cavernous fistula (tCCF) concomitant with pseudoaneurysm in the sphenoid sinus. Six cases of tCCF concomitant with pseudoaneurysm in the sphenoid sinus were analyzed in this study. Clinical history, neurological examination, CT and MRI scans, pre- and postembolization cerebral angiograms and follow-up data were included. ⋯ Intracavernous sinus hypertension of tCCF combining with fracture of the lateral wall of the sphenoid may lead to the formation of a pseudoaneurysm in the sphenoid sinus. MRI scan is very helpful in the diagnosis of this disease before the patient receives angiography. Detachable balloon occlusion of the pseudoaneurysm and fistula is a safe and efficient treatment.
