Intracerebral ganglioglioma

Area of Science:

• Neuro-oncology
• Neurosurgery
• Neuroradiology

Background:

• Gangliogliomas are rare tumors of the central nervous system.
• Temporal lobe gangliogliomas represent a specific subtype with unique clinical and imaging characteristics.

Purpose of the Study:

• To investigate the incidence, clinical presentation, diagnostic imaging features, and treatment outcomes of temporal lobe gangliogliomas.
• To evaluate the utility of Magnetic Resonance Imaging (MRI) in diagnosing and monitoring these tumors.

Main Methods:

• Retrospective analysis of 998 patients undergoing biopsy for intracranial tumors.
• Review of clinical data, electroencephalography (EEG), computerized tomography (CT), and MRI findings.
• Correlation of imaging findings with surgical and pathological data.

Main Results:

• Ganglioglioma was found in 0.6% of patients, predominantly in young adults and children.
• Seizures were the most common symptom, often with a long history.
• CT revealed calcifications in some cases and cystic, well-circumscribed features.
• MRI confirmed cystic and solid components, proving valuable for diagnosis and postoperative assessment.

Conclusions:

• Temporal lobe gangliogliomas are infrequent tumors primarily affecting younger populations.
• MRI is a crucial diagnostic tool, especially for cystic lesions identified on CT, and aids in postoperative monitoring.
• Surgical intervention, aiming for complete tumor resection, is the recommended treatment approach.
