title: Cervical meningeal histiocytosis demonstrated by magnetic resonance imaging.
abstract: Involvement of the central nervous system by histiocytosis X is usually restricted to the parasellar region. A rare case of histiocytosis X involving the cervical meninges in a 12-month-old boy is demonstrated and the magnetic resonance features of this tumor are described.
