Pediatric pseudotumor cerebri.

1. Signs and symptoms of pseudotumor cerebri include papilledema with imaging studies that reveal a normal brain; elevated intracranial pressure with normal cerebrospinal fluid contents; and abducens palsies with diplopia. 2. The most common presenting symptom is headache. Preverbal children may be irritable. Infants often are sleepy or apathetic. Other symptoms include dizziness and ataxia. 3. Loss of acuity or visual field is the only serious permanent complication of pseudotumor cerebri; children often complain of "blurred vision."
