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.
