[Arteriovenous shunting of cerebral blood flow in basal meningo- cerebral developmental anomalies and paraganglioma of the glomus jugulare].

The authors describe a case of angiographically verified arteriovenous shunting of the cerebral blood flow coupled with basal ++meningo-cerebral developmental abnormality and paraganglioma of the glomus jugulare in a 52-year-old patient. Such a unique combination made it possible to suggest the existence of potential mechanisms of blood flow shunting either via tumorous vessels or vessels (arteriovenous shunts) of the basal ++meningo-cerebral developmental abnormality. In the latter case, the shunts were likely to occur latently while the clinical manifestations of the disease might be related to the tumor growth, impairment of the venous outflow and disclosure of arteriovenous shunts.
