Summary:

Description
  • Radiopaedia case ID: 28773
  • Image ID: 6656938
  • Image stack position: 3/20
  • Plane projection: Rt PERI ORB
  • Study findings: Right frontal deep AVM has small nidus from superior division of MCA - small ill-defined, probably from multiple branches (opercular). Single draining vein passes medially, with venous varix, venous stenosis, then into internal cerebral vein and vein of Galen. ECA injection showed no supply, and there was none from the contralateral carotid or vertebral injections. No arterial aneurysms identified. Marked enlargement and retrograde filling of the ophthalmic veins noted on the ECA injection - filling from anterior to posterior - with no evidence of cavernous DAVF. Conclusion: Right frontal AVM with hemorrhage, venous stenosis, single draining vein passing to deep venous system. Small nidus, deep drainage, eloquent = Spetzler & Martin grade III.
  • Modality: DSA (angiography)
  • System: Central Nervous System
  • Findings: Large right frontal intraparenchymal hemorrhage, approximately measuring 6 x 2.5 x 6 cm in perpendicular dimensions; with minimal surrounding vasogenic edema and mild resultant mass effect effacing the sulci. Extension of the hemorrhage into the ventricular system noted with blood layering within the dependent position of the lateral ventricles as well as third and forth ventricles. There is perhaps subtle prominence of the temporal horns bilaterally suggestive of an early hydrocephalus.
