Ganglion cell tumours are mostly seen in children and young people, but they are extremely rare, accounting for 0.1-0.5% of all brain tumours. It usually occurs in the floor of the third ventricle and the temporal lobe. Recently we have experienced a pineal gangliocytoma, probably the first ever seen in Japan and the fourth case in the world, and have succeeded in a total removal of it. The case concerns a 51-year-old man who suffered from intermittent blurred vision and headache of 3 years' duration. CT showed, together with severe hydrocephalus, positive contrast medium enhancement and a somewhat irregular but sharply circumscribed high density lesion suggestive of a meningioma. But the brain scintiscan revealed a badly and irregularly demarcated region of warm activity and having little change with time mainly in the pineal region, which was strongly suspicious of gliomas. Hence this scan was thought to be important in diagnosing this tumour. As an operative procedure, biparieto-occipital craniotomy was successfully performed in the "sea lion" position to remove the tumour totally. Pathological findings indicated a mixture of dispersion and concentration of giant cells possessing prominent nucleoli, abundant chromatin and a prominent nucleus or several nuclei of varying sizes and process-like cell bodies polygonal or irregular in shape. GFAP stain showing no glial fibres and the tumour was thought to be a gangliocytoma.

A case of pineal gangliocytoma in a 51 year-old man is presented. He was admitted to the hospital on February 2, 1982, with complaints of headache, nuchal pain, blurred vision, nausea and vomiting of three years' duration. Neurological examination did not show any neurological deficits but bilateral choked disc. Preoperative CT scan disclosed a sharp by circumscribed high density lesion in the pineal region with moderate hydrocephalus. Preoperative 99m Tc-DTPA brain scan revealed a warm activity in the pineal region, and changes of its activity were only little in the course of time. Preoperative Amipaque ventriculogram showed dilation of the lateral ventricles and a shadow of the tumor bulging into the posterior half of the distended third ventricle. A diagnosis of tumor of the pineal region was made and removal of the tumor was performed by biparieto-occipital interhemispheric approach in "sea lion" position. The tumor was a dark reddish solid mass which replaced the pineal body and extended under the cerebellar tentorium. The patient made an uneventful recovery without any neurological deficits. By light microscopy, the neoplasm was composed mostly of mature and immature ganglion cells and small round cells with moderate cellularity and multiform cytologic features. Ganglion cells with large nuclei and prominent nucleoli had characteristic Nissl substance in various amounts. Oligodendrocytes and astrocytes appeared around the tumor but did not show neoplastic growth. GFAP stain did not show glial component in the tumor. According these findings, the tumor was diagnosed as gangliocytoma originated from the pineal body, and this was the first case in Japan.

BACKGROUND Lhermitte-Duclos disease (LDD) is caused by a rare slow-growing mass in the cerebellum. LDD generally is experienced by young adults, but also it has been encountered in the pediatric population. Lhermitte and Duclos first described cerebellar dysplastic gangliocytoma in 1920. The first case they described included occipital headache, paroxysmal vertigo, falls, hearing problems, and memory deficits. Our patient had typical symptoms of the disorder such as headache, nausea, vomiting, blurred vision, and imbalance. The purpose of this case report was to describe the outcome of a computerized dynamic posturography (CDP) vestibular training program combined with home-based exercises designed to improve balance function and reduce the risk of falling by an individual with a posterior fossa tumor. CASE REPORT A 36-year-old male patient was diagnosed with dysplastic gangliocytoma/ganglioglioma according to magnetic resonance imaging, computed tomography, and pathology reports on March 28, 2016. The patient was treated by partial cerebellar tumor resection on April 7, 2016. After the operation, he reported severe imbalance, nausea, and vomiting for 1 month and visited the Audiology Department on October 20, 2016. The patient was evaluated with the CDP-sensory organization test (SOT) and his composite equilibrium score of this examination was 48, 31% below normal. We administered a 6-week posturography-assisted vestibular rehabilitation (VR) protocol (extending an hour per week) combined with a home-based exercise program twice in 2 years. In the second evaluation we applied in 2018, SOT composite equilibrium score increased to 72 after VR, reaching normal limits. After 2 years, his complaints slightly alleviated and his SOT scores were better when we compared the VR results in 2016. CONCLUSIONS We demonstrated that long-term VR may affect a patient with dysplastic cerebellar gangliocytoma (LDD) presenting imbalance or dizziness.
