Case in brief

A woman in her 40s presented with right-sided hemiparesis, and MRI revealed a left thalamic infarction. Further investigation identified pulmonary arteriovenous malformation (PAVM) associated with hereditary haemorrhagic telangiectasia (HHT) as the underlying cause of her stroke. She underwent successful transcatheter embolisation and has remained free of recurrent strokes while on single antiplatelet therapy.

Diagnostic / clinical pearl

Clinicians should consider pulmonary arteriovenous malformation in young patients with cryptogenic strokes, particularly when no other risk factors are present.
