Group b streptococcus endogenous endophthalmitis presenting as septic arthritis and a homonymous hemianopsia due to embolic stroke

Purpose To report a case of group B streptococcus (GBS) endogenous endophthalmitis in a patient presenting with septic arthritis and a homonymous hemianopsia due to embolic stroke. Design Observational case report. Methods A 75-year-old woman with septic arthritis and a homonymous hemianopsia due to embolic stroke was examined and found to have endogenous GBS endophthalmitis due to bacterial endocarditis. Results Magnetic resonance imaging showed many septic emboli to the brain, including the left occipital lobe. Fundus examination showed evidence for endogenous endophthalmitis. Blood and urine cultures were positive for GBS. A mitral valve vegetation was presumed to be the cause of the intracranial septic emboli and was demonstrated on transesophageal echocardiography. Conclusions Septic arthritis and embolic stroke are suggestive of endocarditis and sepsis. Endogenous endophthalmitis in this case led to transesophageal echocardiography, which was diagnostic for endocarditis.
