Temporal lobe gangliogliomas in children

Area of Science:

• Neuro-oncology
• Pediatric Neurology

Background:

• Gangliogliomas are mixed neuronal-glial tumors with unclear incidence and characteristics.
• They predominantly affect children and young adults, often presenting with seizures.

Purpose of the Study:

• To define the incidence, clinical presentation, radiological features, and natural history of gangliogliomas.
• To evaluate the efficacy of surgical management for these tumors.

Main Methods:

• Retrospective review of 111 primary brain tumors.
• Analysis of clinical data, neuroimaging (CT scans), and treatment outcomes for patients with gangliogliomas.

Main Results:

• Gangliogliomas constituted 9.0% of primary brain tumors in the study cohort.
• The temporal lobe was the most common site; seizures were the universal presenting symptom with patients neurologically intact.
• CT scans revealed partially calcified, isodense masses with minimal enhancement. Complete resection led to significant seizure control.

Conclusions:

• Gangliogliomas are significant causes of seizures in children and young adults, particularly when located in the temporal lobe.
• Complete surgical removal is the primary treatment, yielding excellent seizure control and prognosis.
• Radiotherapy/chemotherapy are reserved for malignant transformations.
