Introduction: Germ Cell Tumors (GCT) represent less than 4% of primary brain tumors. They comprise Germaniums, Non-Germinomatous Germ Cell Tumors and Teratomas. Teratomas represent less than 20% of intracranial GCT. They are tumors of multipotential cells derived from all 3 germ cell layers, frequently arising in midline structures, most commonly in the pineal and suprasellar regions, with a clear excess of male cases and frequently found in children and young adults. We report a case of a mature teratoma in the third ventricle in a 37-year-old male. Case Report: We report a case of a 37-year-old male with a history of headache lasting up to 9 days and refractory to pharmacological treatment. The CT scan revealed a 20mm round hypodense lesion in the anterior third ventricle, with a punctate hyperdensity in the inferior pole causing biventricular hydrocephalus with no periventricular lucency and the MRI showed a well-defined encapsulated mass lesion attached to the roof of the third ventricle, isointense in T1WI with circumferential enhancement and hyperintense in T2WI. Gross total resection was performed. Histopathologic evaluation revealed a mature teratoma. There was no evidence of recurrence on follow up MRI at 2 years. Conclusion: Intracranial teratomas typically originate in midline structures from optic chiasm to pineal region. Presentation after the first two decades of life is exceptional. Complete surgical resection is the only curative treatment for pure mature teratomas. We report the case of a mature teratoma in a 37-year-old male with unusual radiological findings.
