Doctors have reported the first case of CNS bartonellosis with brain abscesses, in a woman whose infection may have stemmed from a cat scratch. 

The 28-year-old patient had presented to an ED in the US, reporting progressive vision loss over a four-month period, which was asymmetric, bilateral and painless. 

She also had a history of SLE and lupus nephritis and was on chronic immunosuppression medication, wrote doctors from the neurology department of Saint Louis University School of Medicine, Missouri.

Two months before the ED visit, her ophthalmologist had increased her prednisone regimen to 80mg daily, with concerns about lupus retinitis.
