Encephalopathy with retinitis due to cat-scratch disease.
Cat-scratch disease is one of several diseases known to be caused by Bartonella species. Some infections due to Bartonella resolve spontaneously without treatment with antibiotics, but in other cases the disease can be fatal without treatment. This case study reports a 7-year-old male who presented with an unexplained encephalopathy and unusual retinal findings associated with evidence supporting infection by B. henselae. The 7-year-old male presented with a 2-week history of general malaise and cervical lymphadenopathy progressing onto fever, headache, vomiting, and confusion associated with meningism. Lumbar puncture revealed a raised cerebrospinal fluid protein, low glucose, and raised white cell count. Abnormal retinal findings and raised antibodies titres to B. quintana indicated a diagnosis of cat-scratch disease. He was treated with azithromycin orally for 3 weeks and made a complete recovery.
