A case of bilateral fourth nerve palsy associated with pseudotumor cerebri syndrome.

ABSTRACT

Pseudotumor cerebri syndrome is puzzling because it results in elevated intracranial pressure with no identifiable underlying cause. Ocular motor nerve palsies, other than a unilateral or bilateral sixth cranial nerve palsy, are rarely seen in patients with this condition. We report here on a 25-year-old female patient with bilateral fourth cranial nerve palsy caused by pseudotumor cerebri syndrome, whose ocular and systemic signs and symptoms of nerve palsy were completely resolved after medical treatment. We infer that fourth nerve palsy could be associated with pseudotumor cerebri syndrome; therefore, clinicians should consider rare ocular motor nerve palsies, even bilaterally, in patients with pseudotumor cerebri syndrome.
