Transverse myelitis associated with herpes simplex virus infection.

The case of an otherwise healthy 6-year-old boy with symptoms and signs of acute transverse myelitis is presented. The diagnosis was confirmed by magnetic resonance imaging. An episode of gingivostomatitis had preceded, and serology indicated herpes simplex virus type 1 infection. The child recovered gradually, and no relapses were noted during a 30-month follow-up period.
