3.A propos 1 case of sudden loss of hearing due to meningioma known as acoustic neuroma (tumor of VIII nerve)
Journal of Practical Medicine 2002;435(11):31-33
Cerebellopontine angle meningioma originates usually from cerebellar tentorium and petrous bone, sometimes expands to the internal auditory canal. In this case, the meningioma extended to the auditory canal and pressed the VIII nerve causing hearing loss suddenly as an acoustic neuroma. Contrast CT-scanning revealed a neuroma with a normal auditory canal. The removed tumor was identified microscopically as a meningioma

4.47 cases of microsurgery operating for the tumor of VIII nerve (acoustic neuroma).
Journal of Practical Medicine 2002;435(11):25-29
47 studied cases aged from 18 to 75 years with a prevailing of women against men were diagnosed by CT-scanning and by MRI. The function of VIII nerve was assessed by clinical examination and by audiogramme. Tumors of VIII nerve occupied 8-10% of the total of intracerebral tumors and 70-80% of all cerebellous angle tumors. Microsurgery manifested good results for facial nerve function on 100% of small tumors, 40% of medium and 22.22% of large tumors. Functional hearing results were also evaluated with respect of the sizes of tumors. Complications of the surgery consisted mainly of cerebrospinal fluid leakage (2.12% of all patients). There were 8 cases of meningitis postoperatively, their 1 died. Complete resection of the tumor was accomplished on 63.8% of patients (consisting of 100% of small, 70% of medium and 61.1% of large tumors).

Acase of trigeminal neuralgia caused by a contralateral acoustic neurinoma is presented. After removal of the tumor, the neuralgic pain has completely disappeared. The pathophysiology of this entity is briefly reviewed. The neuralgic pain may be caused by the compression of the contralateral trigeminal nerve by the mass effect in this case.
