Klebsiella pneumoniae infective endocarditis originating from asymptomatic prostatitis presenting with papilloedema.

SummaryKlebsiella pneumoniae is emerging as a pathogen of global concern due to an increasing incidence of hypervirulent pathotypes causing life-threatening infections, including infective endocarditis (IE). A man in his 30s who was previously fit and well, presented to our eye casualty with headaches, papilloedema and fever. Blood cultures grew K. pneumoniae and transthoracic echocardiography detected IE of the aortic and mitral valves. Fluorodeoxyglucose positron emission tomography revealed focal increased accumulation at the right side of the prostate. The patient was treated for K. pneumoniae subacute IE of the aortic and mitral valves, originating from asymptomatic prostatitis. Our case highlights that young, healthy, immunocompetent patients can develop IE from K. pneumoniae It also demonstrates that papilloedema can be a presenting sign of this disease. To our knowledge, there are no previous reports of IE presenting with papilloedema.
