We report a primary intracranial extra-axial mesenchymal chondrosarcoma in a 16-month-old patient with a review of the literature focusing on intracranial extra-axial MCs with or without skull involvement in pediatric patients, including differential diagnosis. The patient was admitted with a swelling in the right temporooccipital region. There was intracranial extra-dural extension of the mass, which abuts the neural parenchyma without any invasion. A complete tumor resection was performed. Pathological diagnosis was mesenchymal chondrosarcoma. The patient was free of symptoms after surgery.eninfo:eu-repo/semantics/closedAccessHey1-ncoa2 fusionReactivityExpressionTumorsBoneMesenchymal chondrosarcomaCranialExtra-axialChildCTMRINeurosciences & neurologyPediatricsSurgeryReview00053097980000164965737210.1007/s00381-020-04652-0
