CT and MR imaging of the brain and gallium-67 scintigraphy showed ale
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 ser
ologic tests,were positive for cat-scratch disease. Neurologic involve
ment in cat-scratch disease is uncommon, and the presence of organisms
in neural tissue has not been reported.
