A 13-YEAR-OLD Mexican girl was evaluated for a weeklong history of recurrent tonicoclonic seizure activity. The only observation from a medical examination was a small lymph node in the left anterior region of the neck. The girl was alert and afebrile, and findings were normal for complete blood cell count; prothrombin and activated partial thromboplastin times; electrolytes, serum urea nitrogen, creatinine, and glucose levels; and urinalysis. A radiograph of the chest was unremarkable, but a magnetic resonance image of the brain showed a single, small, ring-enhancing lesion surrounded by edema in the subcortical zone of the high left parietal region.
