Pediatric parasagittal meningioma, case report
Abstract
BACKGROUND: Meningiomas are the most common primary tumors of the central nervous system in adults, accounting for up to 40% of intracranial neoplasms. In the pediatric population, however, they are rare, representing only 1-2% of cases. Diagnosis is often delayed due to clinical variability, lack of predisposing factors, and similarity with more frequent conditions such as migraine or demyelinating diseases.
CLINICAL CASE: A previously healthy 16-year-old female with no significant medical history presented with a nine-month history of recurrent headaches, episodes of transient visual loss, and weakness in the lower extremities. An initial clinical suspicion of a demyelinating disease led to a contrast-enhanced magnetic resonance imaging, which revealed an extra-axial interhemispheric parasagittal lesion consistent with meningioma. A bilateral frontal craniotomy with complete resection was performed. In the immediate postoperative period, the patient developed a transient motor deficit and persistent bilateral temporal visual field loss. Histopathological analysis confirmed a WHO grade I meningioma.
CONCLUSION: This case highlights the importance of considering intracranial structural processes in adolescents with progressive neurological symptoms and reinforces that complete surgical resection remains the cornerstone of treatment and the main determinant of functional prognosis.

How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
