Summary:

Description
  • Radiopaedia case ID: 41262
  • Image ID: 17619262
  • Image stack position: 11/16
  • Plane projection: RT CCA NECK
  • Study description: Cerebral angiogram (DSA)
  • Study findings: Procedural notes: 5F Right CFA access. Bilateral internal and external carotid / Bilateral vertebral angiograms. Manual hemostasis. Findings: There is a 1.8 cm AVM nidus within the precentral right frontal lobe. The dominant arterial supply is from an enlarged posterior frontal cortical branch of the anterior cerebral artery, there is additional arterial supply from distal right middle cerebral artery branches. The ACA supply is dysplastic with focal stenosis just before the nidus. No feeding artery or circle of Willis aneurysms identified. No external carotid arterial supply. Venous drainage is superficial, via an enlarged superficial cortical vein to the subjacent superior sagittal sinus. There is no deep venous drainage identified. Bilateral occipital DVA's are incidentally noted. Conclusion: Grade 2 right posterior frontal AVM.​
  • Modality: DSA (angiography)
  • System: Central Nervous System
  • Findings: Technique: Volumetric imaging acquisition through the brain has been obtained pre and post-contrast administration, including CT arterial angiogram. Findings: There is a right superior frontal gyrus arteriovenous malformation characterized by a compact nidus measuring 1,9 cm and being supplied by distal branches from the right ACA and right MCA, and drained by superficial cortical veins that finish at the superior sagittal sinus. There is no signs of acute hemorrhage. The remainder brain parenchyma is unremarkable. Conclusion: Right frontal arteriovenous malformation (Spetzler-Martin grade 2).
