Overview
Ganglioglioma is a rare, slow-growing neoplasm composed of neoplastic glial cells and neoplastic neurons, typically occurring in the cerebral hemispheres, particularly in children and young adults. 1Diagnosis
Clinical Presentation: Often presents with seizures and headaches. 1
Imaging: Characterized by contrast-enhancing masses on CT and MR imaging, frequently with cystic components. 1
Angiography: Typically avascular, though highly vascular cases have been reported, emphasizing the need for differential diagnosis in vascular lesions. 1
Pathology: Confirmed through neuropathological examination identifying neoplastic glial and neuronal elements. 1Management
Surgical Resection: Primary treatment involves complete surgical removal when feasible. 1
Adjuvant Therapy: Not typically required for low-grade gangliogliomas; reserved for recurrent or high-grade cases. 1Special Populations
Pediatrics: Commonly affects children and young adults, with imaging findings as described applicable. 1Key Recommendations
Include ganglioglioma in the differential diagnosis for supratentorial vascular lesions, especially in pediatric patients presenting with seizures and cystic masses on imaging. (Evidence: Weak) 1
Surgical resection should be considered the first-line treatment for localized gangliogliomas to achieve complete removal. (Evidence: Expert opinion) 1
Angiographic findings of vascularity should not exclude ganglioglioma from consideration, as atypical vascular patterns can occur. (Evidence: Weak) 1References
