A 51-year-old woman presented with a rare completely intradural and extramedullary spinal ganglioneuroma associated with multiple hamartoma syndrome and manifesting as complaints of neck pain and dizziness persisting for 8 months. Magnetic resonance imaging of the spinal cord revealed an intradural extramedullary lesion at the C1 level. She underwent right suboccipital craniectomy and C1-2 hemilaminectomy to remove the tumor. Histological examination confirmed ganglioneuroma. She also suffered from multiple facial trichilemmomas, thyroid goiter, multiple polyposis of the gastrointestinal tract, and pulmonary hamartoma indicating multiple hamartoma syndrome. These benign neoplasms were treated conservatively.

Lhermitte-Duclos disease (dysplastic gangliocytoma of the cerebellum) is a rare pseudo-neoplastic disorder of the cerebellum with typical MRI findings. A 25-year-old man presenting with progressive neck pain, dizziness, and impaired vision is reported. CT and MRI revealed a left cerebellar haemispheric mass and obstructive hydrocephalus. Lhermitte-Duclos disease was histologically confirmed after surgical removal of the lesion. The typical MRI appearance of a nonenhancing haemispheric cerebellar mass with preservation and exaggeration of the normal gyral pattern allows pre-operative diagnosis of this condition. The literature is reviewed and clinical presentation, radiology and histopathology are discussed.

We report the case of a patient with pre-existing multiple sclerosis, who presented with horizontal diplopia, and a prior episode of progressive ataxia and dizziness lasting one week. While initially attributed to multiple sclerosis, subsequent imaging demonstrated a concurrent left cerebellar gangliocytoma, also known as Lhermitte-Duclos disease.

A middle-aged man presented with 1-month history of headache, dizziness, staggering of gait and progressive deafness. Examination revealed decreased visual acuity, papilloedema, gaze evoked nystagmus, bilateral sensorineural deafness and gait ataxia. MRI showed TI iso and T2 hyperintensity of cerebellum, prominence of folia with gyral enhancement in a tigroid pattern making impression of the rare entity, Lhermitte Duclos disease (LDD) or dysplastic gangliocytoma of cerebellum. Conservative management for the raised intra cranial pressure did not have any impact on patient's general condition for which an MR venogram was planned and it surprisingly showed non-visualisation of left transverse sinus and internal jugular vein, suggestive of thrombosis. Patient was treated with anticoagulants but he succumbed to his illness soon after. We present this case to convey that a high index of suspicion should always be there in mind for this commoner condition (venous sinus thrombosis) before diagnosing the rarer ones (here LDD disease) to prevent the disastrous consequences of the former.

We report a case of a 60-year-old man who presented with weight gain, headaches, dizziness, erectile dysfunction and decreased libido. He was found to have elevated adrenocorticotropic hormone (ACTH) and prolactin serum levels. The imaging studies revealed a 1.4 cm sella/suprasellar mass which was compressing the optic chiasm. Histologic slides of the lesion showed a pituitary adenoma, marked by a proliferation of biphenotypic appearing cells, associated with a gangliocytoma, and marked by a proliferation of atypical appearing neuronal cells arranged against a glial-appearing background. Pituitary adenoma-gangliocytomas are benign combination tumors that rarely occur in the sellar region. Adenomas in this setting are sometimes functional, and rare patients with mixed adenomas (adenomas secreting more than one hormone) have been reported. To our knowledge, there has been only one other report of a combined ACTH and prolactin-producing adenoma with gangliocytoma, reported in a patient who also had acromegaly. In our patient, the immunohistochemical stains demonstrated that the bulk of the adenoma cells stained with prolactin antibody, and scattered clusters of cells within the adenoma stained positively for ACTH. The adenoma did not stain with antibodies to any of the other anterior pituitary hormones. Postoperatively, the elevated prolactin and ACTH levels returned to normal levels and there was no evidence of residual tumor. Adequate sampling and immunohistochemistry are important in rendering a correct diagnosis and in identifying the hormone status of mixed adenoma-gangliocytomas.

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.
