Cat scratch disease encephalopathy in an immunocompetent patient.
ABSTRACT Cat scratch disease (CSD) is typically a self-limited regional lymphadenopathy in children and young adults that is caused by Bartonella henselae. The majority of CSD cases resolve spontaneously; however, many systemic complications have been described. We report an unusual case of CSD presenting as an epitrochlear arm mass and complicated by encephalopathy. Identification of B. henselae DNA in the affected lymph node and cerebrospinal fluid confirmed the diagnosis of CSD. Systemic antibiotic therapy was administered and the patient improved without any neurological deficit.

ABSTRACT: We detected infection with a Bartonella species (B. henselae or B. vinsonii subsp. berkhoffii) in blood samples from six immunocompetent patients who presented with a chronic neurological or neurocognitive syndrome including seizures, ataxia, memory loss, and/or tremors. Each of these patients had substantial animal contact or recent arthropod exposure as a potential risk factor for Bartonella infection. Additional studies should be performed to clarify the potential role of Bartonella spp. as a cause of chronic neurological and neurocognitive dysfunction.Journal of clinical microbiology 09/2008; 46(9):2856-61.

ABSTRACT: Visceral involvement in absence of lymphadenopathy is a rare manifestation in cat scratch disease; hepatic granulomas are rare, representing 0.3% of systemic manifestations of cat scratch disease, and gallbladder extension is a singular case. The present article refers to 2 rare cases of visceral cat scratch disease in immunocompetent adults with hepatic granulomatous inflammation, caused by Bartonella henselae infection, with gallbladder involvement in 1 case and no lymphadenopathy. Histological features demonstrated the presence of inflammatory necrotizing granulomatous nonneoplastic process. Molecular studies (polymerase chain reaction) were performed to confirm the infectious etiology.International Journal of Surgical Pathology 11/2006; 14(4):349-54.
