Dural arteriovenous fistula at the craniocervical junction with perimedullary venous drainage

M Mascalchi et al. AJNR Am J Neuroradiol. 1996 Jun-Jul.

Abstract

MR imaging showed swelling and diffuse signal changes in the spinal cord in two patients with progressive myelopathy. MR angiography revealed slow-flow perimedullary vessels extending to the skull base, which are consistent with drainage vessels of a dural arteriovenous fistula at the craniocervical junction. This fistula was subsequently seen in both patients on selective arteriograms of the ascending pharyngeal and vertebral arteries.
