title: Childhood atypical meningioma with perineural spread: MR findings.
abstract: Meningiomas are uncommon in children. When they occur, they are frequently associated with neurofibromatosis type 2. Childhood meningiomas are generally large and commonly associated with cyst formation and an unusual location. Perineural tumor spread, occasionally associated with head and neck malignancies, is very rare in meningiomas. We present the MR findings of an atypical meningioma with perineural spread in a 4.5-year-old girl.
