Case in brief
A 14-year-old boy with a large, inoperable left parieto-occipital arteriovenous malformation extending into the temporal lobe had a history of speech delay, ADHD, oppositional behavior, emotional dysregulation, and severe headaches. He developed progressive psychiatric symptoms, including paranoid delusions, disorganized thinking, and behavioral disinhibition. Imaging before a fatal knife attack on neighbors showed AVM progression with cerebral edema. He was diagnosed with psychotic disorder due to a medical condition (AVM). After arrest, he was found incompetent to stand trial and placed in a state psychiatric facility.
What made this case unusual
The report describes homicidal violence in a teenager with an AVM, an association the authors note had not previously been linked to homicidal violence. His developmentally typical, psychiatrically healthy twin brother provided a contrasting family context.
Diagnostic / clinical pearl
Progressive neuropsychiatric symptoms in a patient with a known cerebral AVM warrant attention to the underlying lesion; in this case, imaging showed AVM progression and cerebral edema before psychotic decompensation.
Why it matters
The case illustrates the complexity of relating focal brain pathology to violent behavior, which the authors emphasize has multifactorial origins.
