Introduction: Mycotic pseudoaneurysms are an infrequent complication of infective endocarditis; most cases are secondary to arterial trauma. The commonest site involved are the intracranial arteries, followed by the abdominal aorta and then the peripheral vessels.
Case Presentation: We report a case of a 36-year-old man, admitted in our institution for a subarachnoid haemorrhage, who presented with fever of unknown origin during his stay in the neurocritical care unit and whom was diagnosed infective endocarditis due to Meticilin Sensible Staphylococcus Aureus.
