Abstract
PURPOSE:
To describe the characteristics of enhanced magnetic resonance imaging of the orbit in a patient with acute paralysis of the inferior division of the oculomotor nerve.
METHOD:
Using a fat-suppression technique, we performed enhanced magnetic resonance imaging of the orbit of a 36-year-old woman with acute paralysis of the inferior division of the left oculomotor nerve.
RESULTS:
The inferior division of the left oculomotor nerve in the orbit was markedly enhanced, suggesting inflammation of the inferior division of the oculomotor nerve. The severity of paralysis decreased immediately after intravenous corticosteroid (prednisolone acetate) administration.
CONCLUSION:
These findings suggest that enhanced magnetic resonance imaging with a fat-suppression technique is useful for diagnosing peripheral nerve lesions in the orbit.
