Posterior fossa clear cell meningioma without dural attachment in a child.

Introduction: Meningiomas are relatively uncommon in childhood. They represent 1% to 2% of all intracranial tumours of infancy and childhood and 1.5% to 1.8% of all intracranial meningiomas. Occasionally, meningiomas may develop without dural attachment. Clear cell meningioma is a histological distinctive uncommon variant of meningioma that may behave aggressively with local recurrence and progression as well as cerebrospinal fluid-borne metastasis. Meningiomas near the craniocervical junction represent challenging tumours, requiring special considerations because of the vicinity of the medulla oblongata, the lower cranial nerves and the vertebral artery.

Case Report: In this study, the authors present a rare case of posterior fossa clear cell meningioma without dural attachment in a child with severe brainstem and cervical spinal cord displacement and discuss the clinical and radiological features as well as treatment considerations.
