An unusual agent for an unusual localization of infective endocarditis

We report on a 32-year-old male patient with acute left-hemispheric stroke caused by embolism due to infective endocarditis affected from the HACEK group. Additionally, atypical findings from the transesophageal echocardiography (TEE) which showed fluttering structures belonging to the papillary muscle could be proven as infectious agents with the help of a glucose positron emission tomography (PET) scan. TEE controls showed increasing vegetation involving the mitral valve so that surgery became necessary. The current work reflects, in detail, the emergent clinical course of this young patient, suffering from both an unusual localization and an infrequent cause of endocarditis and focuses on an actual view to the literature.
