• Abstract: Introduction: Intracranial teratomas are rare germ cell tumors, accounting for approximately 0.5% of all intracranial tumors. They can be classified as mature, immature, or malignant, and are typically located along the midline of the brain, particularly around the third ventricle, pineal region, and suprasellar area. Case Report: A 20-year-old female patient presented with a history of seizures, headache, nausea, vomiting, and diplopia. A cranial MRI revealed a multicystic lesion in the left lateral ventricle with ventricular dilation. Surgery was performed with an interhemispheric approach and partial resection of the lesion, confirming the diagnosis of a mature teratoma. The patient had a favorable recovery with no neurological deficits. Discussion:Intracranial teratomas are rare, representing 0.5% of brain tumors, with peaks of incidence before the age of 5 and between 5 and 14 years. They are typically benign and radioresistant. Surgical resection is the primary and curative treatment, with a high survival rate. MRI is useful for characterizing the lesion. Conclusion:Intracranial teratomas are rare and must be differentiated from other germ cell brain tumors. Complete surgical resection is curative and results in good survival rates without the need for further interventions.
