The authors present the case of a 33-year-old patient with a bifocal ganglioglioma located in the right superior temporal gyrus. He had a history of tonic-clonic seizures and developed intermittent nausea and vertigo later on. Magnetic resonance imaging showed two distinct, small lesions in the right temporal lobe. Both tumors were removed microsurgically with ultrasound guidance. Intraoperatively, two distinct tumors were found. Histological diagnosis of both tumors was of ganglioglioma WHO II. Postoperatively, the patient was free of symptoms. Bifocal occurrence or the coincidence of two distinct gangliogliomas is a very uncommon finding. So far, it has not yet been reported in benign gangliogliomas.

Ganglioglioma is a rare central nervous system neoplasm representing 0.4% to 1.7% of all brain tumors and most frequently occurs in the pediatric population with an incidence of 7.6%. These tumors are usually slow-growing and well-circumscribed solid or cystic lesions. Gangliogliomatosis infrequently occurs in the frontal lobe, pineal gland, basal ganglia, hypothalamus, and optic chiasm, with very few reports of brainstem ganglioglioma. We report a case of a 35-year-old female who initially presented with headache, vertigo, ataxia, saccadic dysfunction, dysarthria, and dysmetria for several years due to an unknown etiology. Her brain imaging showed multiple lesions in the pons and the cerebellum with cystic changes and size reduction and enlargement over the next few years while her neurological symptoms continued to worsen. The patient received courses of steroid treatment that improved her neurological symptoms, suggesting an inflammatory component of her disease. Extensive workup for an inflammatory or infectious etiology was unfruitful and two brain biopsies were inconclusive. A third biopsy showed atypical glial nuclei, binucleated cells, and Rosenthal fibers and the presence of BRAF V600E mutation was detected. The diagnosis of gangliogliomatosis was consequently established. This case illustrates that gangliogliomatosis may present with the waxing-and-waning neurological signs and symptoms. It can masquerade inflammatory processes in the central nervous system on brain imaging and deserves careful consideration in the diagnosis of patients with an indolent course of neurological deterioration.

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.
