Diagnosis and interpretation of testing for cat scratch disease
1Baylor College of Medicine, Houston, Texas.
Abstract:
Cat scratch disease (CSD) is an infectious disease caused by Bartonella henselae that presents as regional lymphadenopathy which can appear within weeks after a cat scratch. There is no gold standard for diagnosis. Rather, clinicians rely on an amalgam of criteria to make a definitive diagnosis. We describe a case of a 44-year-old woman with six cats who presented with a painful left inguinal mass, had splenic lesions on imaging, and had positive serology but a negative polymerase chain reaction test for B. henselae.
