1. Purpose:To analyse MRI manifestations of trigeminal neurinoma.

2. Results The trigeminal neurinoma could be classified into three types: posterior cranial fossa type (8 cases), middle cranial fossa type (4 cases), and straddle type (24 cases).

3. The resection of huge acoustic neurinoma with nerve function reserving that has advanced the country levels.

4. Two of seven studies into acoustic neurinoma (a benign tumour of a nerve between the ear and brain) reported a higher risk after using mobiles for 10 years.

5. Objective: To study the early diagnosis of cystic neurinoma at the craniocervical junction and surgical treatment.

6. Pleural neurilemmoma, neurinoma and pleural fibrolipoma usually had the characteristics of benign neoplasm.

7. Objective:To investigate the diagnosis and treatment of neurinoma of the head and neck.

8. Methods 35 cases of large acoustic neurinoma treated microsurgically were analyzed retrospectively.

9. Aim:To raise the removal degree and to improve the postoperative result of MP (middle and posterior fossae) trigeminal neurinoma.

10. Conclusi ons:MRI and DSA are very important in the diagnoses of the oculomotor nerve neurinoma . The best effective treatment may be achieved after selecting the proper approach.

11. Purpose:To elucidate the diagnoses and treatment of the oculomotor nerve neurinoma .

12. Objective: To explore the clinical diagnosis and surgical experiences on management of the intraspinal neurinoma .

13. Conclusion The most common tumors in jugular foramen region are neurinoma, tumor of glomus jugulare, and meningioma. Surgery is effective in treatment of brain tumor in jugular foramen region.

14. Methods: The clinical materials of different pathological types of intraspinal tumors including neurinoma , meningioma, glioma, angioma and lipoma were comprehensively studied on 77 patients.

15. METHODS The clinical data of 19 patients wi th neurinoma of the head and neck in our department from 1990 to 2000 were retrospectively analyzed.

16. Pathological types include 13 cases of meningioma, 6 of neurinoma, 1 of chordoma, 1 of choroid plexus papilloma, and 1 of hemangiopericytoma.

17. Purpose : To explore the histological origin and biological characteristics of acoustic neurinoma on ultrastructural basis.

18. Objective To analyze CT and MRI manifestations of intracranial trigeminal neurinoma .

19. Our study was disigned to evaluate the features of the enhanced MRI in subdural extramedullary neurinoma and the correlation between its enhanced MRI and pathologic findings.

19.

20. Conclusion The MRI have unique advantages in the diagnosis of intraspinal neurinoma.

21. Purpose:This paper approached the value of X-ray, CT, MR for the diagnosis of trigeminal neurinoma.

22. To analyse the clinical characteristics of intramedullaryneurinoma, search for the appropriate microinvasive surgery methods, and improve the diagnosis and treatment of intramedullary neurinoma.

23. Results Extramedullary tumors were found in 34 cases, mainly including neurinoma and meningioma, and intramedullary tumors in 5 cases.

24. OBJECTIVE To study the clinical symptom, diagnosis and treatment of the neurinoma of the head and neck.
