Gangliogliomas are rare brain tumors that have both neuronal and glial components. They hold a better prognosis than other infiltrative glial tumors, but differentiating between them can be challenging. While molecular markers are being studied, it is currently a histologic diagnosis.
In this case, the patient presented with epilepsy and worsening seizures secondary to a medial temporal lobe mass. Radiology report was inconclusive. Surgical resection was achieved and based on histologic examination the lesion was diagnosed as ganglioglioma, WHO grade I.
In this patient, pathological diagnosis of ganglioglioma offers a favorable prognosis and low risk of recurrence. In the future, molecular analysis including determination of IDH-1 and BRAF gene status will allow for more accurate diagnosis in these patients.
