Introduction: teratomas are non-malignantgerm cell tumors commonly composed of cell types derived from all of the three germ layers. Intracerebral teratomas typically are midline or paraxial lesions located in the pituitary stalk or the pineal region. We report our experience with mature teratomas of the posterior fossa. Case report: we present the case of an 11-year-old caucasian female with progressive headache that caused interrupted sleep. Cerebral magnetic resonance imaging showed a midline lesion in the posterior fossa with mass effect and without contrast enhancement. Anatomic pathology revealed a mature teratoma. Conclusion: differential diagnosis of midline lesions in pediatric patients must include teratomas in spite of being posterior fossa lesions.
