De novo twig-like middle cerebral artery after suspected M1 dissection in early childhood with coexisting KRAS-mutated brain arteriovenous malformation: illustrative case

Key Points

• This case examines the formation of a twig-like middle cerebral artery after M1 dissection in a child with a KRAS-mutated AVM.
• Case study design with detailed angiographic analysis.
• Assessment of cranial vascular anatomy through imaging techniques.
• Evaluation of genetic mutations related to vascular remodeling.
• Formation of a postnatal twig-like MCA observed following focal M1 injury.
• Possibly misclassified as congenital in late angiograms.
• Presence of KRAS mutation suggests a potential link to vascular genetic remodeling capabilities.
