Central Nervous System Involvement in Cat Scratch Disease

Abstract

Cat scratch disease is a cause of benign regional adenopathy which is rarely associated with CNS complications. Two children with cat scratch disease associated with alterations of mental status and convulsions are presented. One patient had a focal cerebral abnormality on neurologic examination, EEG, and computed axial tomography. The spectrum of CNS involvement is reviewed for this usually benign disease. Prognosis is generally excellent. The pathogenesis of the CNS complications has not been elucidated.
