A rare diagnosis in ED: cerebral pyogenic ventriculitis due to infective endocarditis

Blood and CSF cultures were obtained, and intravenous ceftriaxone and metronidazole were administrated for the diagnosis of pyogenic ventriculitis. Because the patient had a history of mitral valve prolapse, intermittent fever in the ED, and systolic murmur on examination, transesophageal echocardiography was performed. Symptoms, physical examination findings, and CSF analysis of pyogenic ventriculitis are nonspecific. [...]differential diagnosis between ventriculitis and other central nervous system infection should only be made with imaging studies.
