Transient oculomotor paralysis in pseudotumor cerebri
Neurology
|February 1, 1981
Summary
A patient with pseudotumor cerebri experienced sudden oculomotor paralysis. This rare third-nerve palsy, previously unreported in pseudotumor cerebri cases, may indicate increased intracranial pressure.
Area of Science:
- Neuro-ophthalmology
- Neurology
Background:
- Pseudotumor cerebri (idiopathic intracranial hypertension) is characterized by elevated intracranial pressure without an identifiable cause.
- Oculomotor nerve (cranial nerve III) palsy can result from various neurological conditions, including increased intracranial pressure.
Observation:
- A case report detailing a patient with a history of pseudotumor cerebri who developed acute onset oculomotor paralysis.
- Exclusion of other potential causes for the third-nerve palsy was performed.
Findings:
- Transient oculomotor paralysis occurred abruptly in the patient.
- While sixth-nerve palsy is a known complication of pseudotumor cerebri, third-nerve palsy has not been previously documented in association with this condition.
Implications:
- This case suggests that third-nerve palsy, like sixth-nerve palsy, may be a manifestation of pseudotumor cerebri.
- The occurrence of oculomotor paralysis in this context could serve as a nonspecific indicator of elevated intracranial pressure, warranting further investigation.
