title: Cat-scratch disease with an extraaxial mass.
abstract: CT and MR imaging of the brain and gallium-67 scintigraphy showed an enhancing, gallium-avid mass in the left middle cranial fossa of a 10-year-old girl. Craniotomy revealed an inflammatory mass related to the left trigeminal nerve. The lesion contained rodlike bacteria, and serologic tests were positive for cat-scratch disease. Neurologic involvement in cat-scratch disease is uncommon, and the presence of organisms in neural tissue has not been reported.
