Enhanced magnetic resonance imaging in a patient with acute paralysis of the inferior division of the oculomotor nerve.
OBJECTIVE
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.


METHODS
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.


CONCLUSIONS
These findings suggest that enhanced magnetic resonance imaging with a fat-suppression technique is useful for diagnosing peripheral nerve lesions in the orbit.
