N2 - Young onset stroke is uncommon, and may be due to conditions other than traditional vascular risk factors. A 42-year-old woman with an ischaemic stroke was found to have left atrial bubble study positivity on transthoracic echocardiogram (TTE) suggestive of patent foramen ovale, however she also had low peripheral oxygen saturation. Investigation revealed an isolated pulmonary arteriovenous malformation (PAVM), visible on admission chest radiograph. This can cause embolic stroke and is an alternate cause of the TTE findings. The PAVM was able to be closed via endovascular intervention, removing the shunt and therefore removing her risk of recurrent stroke events. This is a rare cause of embolic stroke in young people which can be easily missed on investigation yet is amenable to treatment.
