  • Title: Challenging dogma: report of a spinal cord arteriovenous malformation as an acquired lesion in a pediatric patient.
    Author: Brinjikji W, Ahn ES, Patterson MC, Lanzino G.
    Journal: J Neurosurg Spine; 2020 Feb 01; 32(2):302-304. PubMed ID: 31653811.
    Abstract:
    Spinal cord intramedullary arteriovenous malformations (AVMs) have classically been considered congenital lesions that are present from birth. The reason for this dogmatic principal is the fact that a vast majority of these lesions present in pediatric and young adult patients. Interestingly, while many authors have demonstrated the development of de novo nidus-type brain AVMs, there have been no reported cases of a de novo intramedullary or perimedullary AVM of the spine. In this paper the authors describe what they believe to be the first reported case of a de novo AVM of the spinal cord in a young patient who underwent serial imaging from birth for evaluation of a syrinx. Potential pathophysiological mechanisms for the development of de novo vascular malformations of the spinal cord are discussed.
