The cause of cat scratch disease (CSD), first described in France in 1950 and in the United States in 1951, was unknown until 1983 when the bacterium in lymph nodes was detected using a Warthin-Starry silver stain. Afipia felis has been an infrequent cause of CSD since1988, when this gram-negative bacterium was first isolated from 10 patients with CSD. In 1992 Bartonella organisms were isolated from immunocompetent and immunocompromised patients. An indirect fluorescent antibody test to detect bartonella-specific serum immunoglobulins was developed in 1992. Since then multiple studies have shown that three Bartonella species may produce either CSD in humans, usually Bartonella henselae or Bartonella clarridgeiae, or bacteremia in healthy cats. Also, these two bacteria and Bartonella quintana cause bacillary angiomatosis, bacillary peliosis, or relapsing bacteremia in humans. Cats are healthy carriers of Bartonella organisms and may be bacteremic for months to years. Cat-to-cat transmission of Bartonella organisms involves the cat flea in absence of direct contact transmission. CSD is the most common cause of regional lymphadenitis in children and adolescents. Present knowledge on the etiology, clinical features, epidemiology, pathogenesis, diagnosis, and management of CSD are presented. Also, brief comments about the etiology, clinical presentation, and treatment of bacillary angiomatosis and bacillary peliosis are provided.

Catch-scratch disease (CSD) is a self-limiting zoonotic illness. Encephalopathy is the most common neurologic manifestation of CSD. Neuroimaging is usually normal with occasional abnormalities reported in children involving the cerebral cortex and thalamus but not previously described in the basal ganglia. Here we report a 7-year-old boy with CSD encephalopathy who developed choreoathetosis with high intensity changes in basal ganglia on magnetic resonance imaging scan.
Cat-scratch disease is an illness caused by Bartonella henselae that occurs as a result of contact with an infected kitten or dog, such as a bite or scratch. It is more prevalent in children and young adults, as well as immunocompromised individuals. There are limited publications examining the features of CSD in patients. As such, the purpose of this research was to assess the clinical neuro-ophthalmological consequences of CSD reported in the literature. Among the ophthalmologic disorders caused by cat-scratch disease in humans, Parinaud oculoglandular syndrome, uveitis, vitritis, retinitis, retinochoroiditis and optic neuritis are the most prevalent. The neurological disorders caused by cat-scratch disease in humans include encephalopathy, transverse myelitis, radiculitis, and cerebellar ataxia. The current review addresses the neuro-ophthalmological clinical manifestations of cat-scratch disease, as described in papers published over the last four decades (1980–2022). All the data gathered were obtained from PubMed, Medline and Google Scholar. The current descriptive review summarizes the most-often-encountered clinical symptomatology in instances of cat-scratch disease with neurological and ocular invasion. Thus, the purpose of this review is to increase knowledge of cat-scratch disease’s neuro-ophthalmological manifestations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
