Gangliogliomas typically arise in the cerebral hemispheres, but may occur rarely in the ventricles. Herein, we report a 38-year-old woman who was treated for hydrocephalus caused by a ganglioglioma of the third ventricle. Magnetic resonance imaging (MRI) revealed a heterogeneously enhanced tumor occupying the anterior part of the third ventricle. A left trans-lateral ventricular trans-foramen of Monroi approach was effective in achieving subtotal resection of the tumor, which had arisen from the medial part of left thalamus to the hypothalamus. Follow-up MRI showed no recurrence of the tumor 5-years after surgery. On pathological examination, the tumor was composed of a glial component that presented features mimicking pilocytic astrocytoma with proliferations of large gangliocytic cells that stained positive for neuronal markers. A review of six similar cases in the literature, including our own, revealed hydrocephalus to be the main symptom of gangliogliomas, with pituitary insufficiencies and visual disturbances having also been reported. In conclusion, we highlight the importance of gangliogliomas in the differential diagnosis of third ventricular tumors presenting with hydrocephalus.
