Presentation of basilar artery stroke secondary to patent foramen ovale: a diagnosis made with a 'selfie'

Aoife Casey et al. BMJ Case Rep. .

Abstract

We report the case of a woman in her late 20s, with no significant medical history, who was found unresponsive at home. Her mother revealed a 'selfie' sent to her by the patient 30 min prior to collapse which revealed bilateral ptoses. Initial brain imaging with non-contrast CT of the brain revealed nil of note. A multiphase CT angiogram revealed an acute basilar artery thrombosis. She underwent timely thrombolysis and was transferred for endovascular thrombectomy. Further evaluation with an aim to define the aetiology revealed the diagnosis of patent foramen ovale with a resultant paradoxical embolism. The differential diagnoses of unexplained rapidly evolving neurology with reduced Glasgow coma scale, and relevant appropriate investigations are discussed in this case report.
