BACKGROUND: Intracranial dural arteriovenous fistulas (dAVFs) are pathological anastomoses between meningeal arteries and dural venous sinuses or cortical veins. Diagnosis of dAVFs can be challenging due to their broad range of clinical manifestations and the lack of specificity in their symptoms. We present a rare case of a patient with bilateral dAVFs, who was referred to our department for carotid doppler ultrasonography/transcranial color Doppler.
CASE REPORT: A 67-year-old man was referred by his treating physician for neurovascular ultrasonography due to vision impairment associated with papilledema of both eyes. On ultrasound examination both external carotid arteries showed a "pseudo-internalization" pattern with high end-diastolic velocities and reduced resistance indices. Subsequent magnetic resonance and digital subtraction angiography revealed dAVF of both transverse sinuses, with occipital and medial meningeal arteries as feeders.
CONCLUSIONS: Neurovascular sonography may serve as a screening and follow-up tool when a DAVF in the transverse sinus/sigmoid sinus is suspected.
