Aqueductal stenosis: a possible late sequela of central nervous system inflammation in systemic lupus.

We have described a patient with a history of central nervous system lupus who had obstructive hydrocephalus secondary to stenosis of the aqueduct of Sylvius. The course of this patient's neurologic disease suggest that the obstruction was caused by a post-inflammatory lesion of CNS lupus. This report illustrates the importance of a complete neurologic evaluation of a patient with SLE who has CNS dysfunction.
