“…Ganglioglioma is the most common pathological tumour type in previous reports; others include hamartoma and astrocytoma. Coincidentally, ganglioglioma is also the most common pathological tumour type that causes epileptic seizures among supratentorial tumours 5,6 Gangliogliomas consist of clusters of dysplastic ganglion cells and abnormally proliferating glial cells of different components. Studies have shown that these slow-growing low-grade gliomas are more associated with seizures than high-grade gliomas, brain metastases and central nervous system lymphomas, possibly related to their ability to modulate neuronal excitability 7 .…”

Objective To investigate the treatment plan and prognosis of children with ocular dyskinesia and hemifacial spasm secondary to pontine tumours adjacent to the fourth ventricle. Methods In this retrospective study, the clinical information of 10 consecutively collected children with ocular dyskinesia and hemifacial spasm secondary to pontine tumours adjacent to the fourth ventricle was analysed. All 10 children underwent pontine tumour resection through a transcerebellomedullary fissure approach; 4 children underwent preoperative diffusion tensor imaging scans to determine the relationship between the tumour and facial nerve nucleus, and the other 6 children underwent intraoperative deep electroencephalography (EEG) tumour monitoring, in which the tumour electrical discharge activity of the tumour was recorded. A voxel distribution map was established to describe the distribution of the tumour location, and patient prognosis was evaluated through clinical and imaging follow-up. Results All 10 children achieved total tumour resection; 9 tumours were pathologically suggested to be ganglioglioma (WHO grade I), and 1 was a hamartoma. The symptoms of the original ocular dyskinesia and hemifacial spasm disappeared immediately after the operation. The children were followed up for 4–75 months, and none of the symptoms recurred; four cases with preoperative diffusion tensor imaging showed that the tumour was close to the facial nerve. Four in six intraoperative electrophysiological monitoring showed that the tumour had electrical discharge behaviour, and the tumor distribution map indicates a high density of tumor presence in the facial nerve nucleus and the nucleus of the abducens nerve. Conclusions In paediatric patients, the facial symptoms are related to the location and abnormal electrical discharge of the tumour. No significant correlation between ocular dyskinesia and the location of the tumour. Conventional antiepileptic therapy for this disease is ineffective, and early surgical intervention for total tumour resection can achieve a clinical curative effect.
