Bilateral cavernous aneurysms. Discussion of a problematic case with review of the literature

<< Mirror >> cavernous aneurysms are exceptional; only 66 such cases having been published until mid-1996. We report on a 68-year-old woman who presented for left exophthalmos, diplopia and neuralgia. MR and angiography demonstrated a giant symptomatic aneurysm on the left side and an incidental small one on the right side. The patient was treated in two sessions : first, she had selective embolization of her right aneurysm; two weeks later, her left carotid artery was sacrified with detachable balloons: after a well-tolerated occlusion test. This original and successful approach permitted to achieve a reasonable goal when considering the patient's age, operative morbidity, risk of future complications and final result. A review of the pathophysiology, clinical manifestations and therapeutic indications is presented and discussed.
