Fifteen-year-old girl with systemic lupus erythematosus and unilateral cerebellitis.

Cerebellar involvement in systemic lupus erythematosus has rarely been described as one of the neurologic manifestations. There has been only one previous pediatric case of cerebellar edema reported in the literature. The differential diagnosis, magnetic resonance imaging findings and treatment modalities are described in the case of a 15-year-old girl who presented with headache, vomiting, unsteady gait, and sudden change in mental status.
