1/7. meningioma of the lateral cerebral ventricle. A case report.The authors present the case of a 58-year-old woman. At presentation the patient complained of vertigo and noise in the ears with six months history, and from headache, accompanied by nausea and vomiting from three months. The physical examination of the patient found no abnormalities. The neurological examination revealed discoordination syndrome and mild hemiparesis of the left limbs. Computed tomography of the brain without and with contrast medium showed oval tumor, localized in the region of trigonum collaterale and the posterior horn of the right lateral ventricle. Operative intervention was performed after a preoperative management of the patient: transcortical fenestration of the brain in the region of trigonum collaterale and the posterior horn of the right lateral ventricle. The tumor was totally removed. It is well isolated, oval in shape, with feeding blood vessel from plexus chorioideus and was attached to the wall of the ventricle with several thin bridges. Macroscopically the tumor was 3 cm in diameter, with smooth walls, well capsulated, grey-brownish in color and with firm elastic consistence. The histological findings revealed meningioma--meningotheliomatose variant.- - - - - - - - - - ranking = 1keywords = vertigo (Clic here for more details about this article) |
2/7. Reversible bilateral vestibular impairment caused by fourth ventricle epidermoid tumor.A 26-year-old man presented with an epidermoid tumor of the fourth ventricle manifesting as headache with nausea and vertigo. Neurological examination revealed no cerebellar signs, except nystagmus. Bilateral vestibular impairment was identified by the caloric test. The tumor was removed via the midline suboccipital approach. The bilateral peripheral vestibular function recovered remarkably postoperatively. This marked improvement suggests that the bilateral vestibular impairment was caused by compression of the vestibular nuclei by the tumor.- - - - - - - - - - ranking = 1keywords = vertigo (Clic here for more details about this article) |
3/7. germinoma-unusual presentation: a case report.germinoma accounts for two-thirds of germ cell tumors and about 40% of all pineal region neoplasms. This case illustrates an unusual manifestation of metatastic germinoma with spread to ventricles and meninges without a pineal mass. A 24-year-old man presented with nausea, vertigo, and left facial droop. cerebrospinal fluid aspirate showed malignant cells most suggestive of a germinoma.- - - - - - - - - - ranking = 1keywords = vertigo (Clic here for more details about this article) |
4/7. A 21-year-old female with a third ventricular tumor.A 21-year-old female presented with a 2-months history of tinnitus, vertigo and nausea. On magnetic resonance imaging of the brain, she demonstrated a small contrast-enhancing mass in the posterior part of the third ventricle. Intraoperatively, the tumor showed a close relationship to the choroid plexus of the third ventricle. Histopathology revealed a benign schwannoma of world health Organization grade I. To our knowledge, only 9 cases of intraventricular Schwann cell tumors have been published so far. Most of these tumors were benign schwannomas, except for 2 cases of malignant peripheral nerve sheath tumors. The tumor of our patient is the first reported schwannoma of the third ventricle. The origin of intraventricular Schwann cell tumors is unknown. They may arise from autonomic perivascular nerves in the choroid plexus or from ectopic neural crest-derived cells. Histologically, intraventricular schwannoma needs to be distinguished from other spindle cell tumors, in particular pilocytic astrocytoma and fibroblastic meningioma.- - - - - - - - - - ranking = 1keywords = vertigo (Clic here for more details about this article) |
5/7. Cerebellar hemangioblastoma and subependymoma: a case report of an unprecedented association.We report the case of a 71-year-old man who suffered from both a cerebellar hemangioblastoma and a subependymoma (glomerate subependymal astrocytoma) of the base of the fourth ventricle. His symptoms included episodes of loss of consciousness, cerebellar ataxia, and postural vertigo. The clinical diagnosis presented considerable difficulties. The simultaneous occurrence of both tumors in one patient has not been reported previously. After reviewing the literature, we conclude that this unusual association was a result of chance rather than common oncogenic factors.- - - - - - - - - - ranking = 1keywords = vertigo (Clic here for more details about this article) |
6/7. Vestibular and oculomotor disturbances in pathology of the fourth ventricle.Positional nystagmus of the central type and gaze paretic (gaze evoked) nystagmus have been reported in pathology of the posterior fossa. It has also been reported that positional nystagmus of the central type is only infrequently accompanied by vertigo and nausea. In this paper five cases are discussed which showed positional nystagmus of the central type and/or gaze paretic nystagmus. All cases showed severe vertigo, nausea and vomiting in the provocative head position. In four out of five cases the pathology was found to be in the area of the IVth ventricle. On the basis of recent neurophysiologic data an attempt is made to explain the manifestations of this pathology. It is concluded that positional nystagmus of the central type is presumably due to pathology of the IVth ventricle area. Also, that this type of nystagmus may be accompanied by severe vertigo, nausea and vomiting.- - - - - - - - - - ranking = 3keywords = vertigo (Clic here for more details about this article) |
7/7. Ependymomas of the third ventricle.Third ventricular ependymomas are rare tumors that have not been specifically examined. Four cases of these tumors are reported. The presenting symptoms included headache, ataxia, vertigo, and Parinaud's syndrome. All the patients underwent computed tomographic scanning and cerebral angiography, followed by craniotomy and microsurgical resection of the tumor. In addition, all patients had or developed symptomatic obstructive hydrocephalus requiring shunting procedures. Three of the patients are alive with a follow-up of 4 to 12 years. It is remarkable that these tumors are so rare, given that the ependymal surface area of the third ventricle is greater than that of the fourth. The management of these tumors should include aggressive surgical resection, radiation therapy, and cerebrospinal fluid diversion.- - - - - - - - - - ranking = 1keywords = vertigo (Clic here for more details about this article) |
