Summary:

Description
  • Radiopaedia case ID: 55798
  • Image ID: 32940394
  • Image stack position: 54/70
  • Plane projection: Axial
  • Aux modality: T1
  • Study findings: Right superior frontal gyrus arteriovenous malformation extending into the right superior frontal sulcus and right precentral sulcus. It contacts the anterior surface of the right precentral gyrus close to the motor cortex location of hand movement. Medially curvilinear signal loss with blooming on the susceptibility sensitive sequence indicating the presence of blood products/hemosiderin and suggests prior hemorrhage/leak. Minimal surrounding high T2 signal in keeping with a small amount of gliosis. Arterial supply from dilated branches from the right middle cerebral and anterior cerebral arteries. There is superficial venous drainage via superficial cortical veins to the superior sagittal sinus. There is no MRI evidence of deep venous drainage.
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Posterior right frontal lobe arteriovenous malformation without hemorrhage or adjacent edema.
