Bilateral internuclear ophthalmoplegia in systemic lupus erythematosus.

Internuclear ophthalmoplegia has been infrequently described in patients with systemic lupus erythematosus. We report a 23-year-old woman with lupus who presented with bilateral internuclear ophthalmoplegia and skew deviation. Additional neurologic findings included dysarthria, hemifacial weakness, hemiparesis, and dysmetria. Computed tomography of the patient's brainstem was unremarkable while magnetic resonance scanning demonstrated two areas of infarction. Magnetic resonance imaging is superior to computed tomography in both neuroradiographic study of the brainstem as well as evaluation of patients with neurologic complications of lupus.
