Background: Meningiomas arising in pediatric populations are rare neoplasms with distinct biological and clinical features. A rare case of a 2-year-old boy with extremely large intracranial parasagittal meningioma is presented. To our knowledge, this case is the largest parasagittal meningioma to be reported to date in the pediatric age group.
Case description: The tumor size at its largest diameter was 14.2 cm. Two-stage craniotomy was performed within 3 weeks to resect the tumor totally by Simpson grade II while preserving the superior sagittal sinus. Three months after the second resection, the patient had a complication of subdural hematoma, which was managed by external drainage and urokinase.
Conclusions: The patient's postoperative recovery was unremarkable, and the previously compressed brain rebounded. There was no evidence of recurrence after two years of follow-up. Every effort should be exerted to achieve radical resection of the tumor, which can result in a satisfactory prognosis and a low recurrence rate.
