Loss of Consciousness Caused by a Rare Etiology: Serratia marcescens Endocarditis

Abstract

Serratia marcescens is an uncommon cause of infective endocarditis and is associated with a rapidly progressive clinical course, early embolic complications, and high mortality. Its initial presentation with neurological symptoms rather than cardiac manifestations is particularly rare and contributes to diagnostic delay. We report a 46-year-old male with multiple coagulation factor deficiencies who was receiving intermittent hemodialysis via a subclavian catheter.
