Abstract

Purpose

This article aims at evaluating the results of treatment which excise the intradural extramedullary tumor using surgical microscope, mainly concerned by the field of orthopaedic surgery.

Materials and Methods

A retrospective review was carried out on 11 cases who were operated on for the excision of intradural extramedulary tumor in two hospitals from June 2001 to May 2007. Of the 11 cases, there were 3 males, and 8 females with an average age of 62.4 (33-78) years. Average follow-up period is 18.8 (1-78) months. Patients were diagnosed by MRI and pathological diagnosis was analyzed. The clinical evaluation was made by the index of VAS (visual analogue scale) and Cooper-Epstein grade.

Results

7 cases were Schwannoma and 4 cases were meningioma. The VAS take a favorable turn from average 9.4 before practice to final follow-up 2.4, and the Cooper-Epstein grade take a favorable turn from average 2.4 to final follow-up 0.7

Conclusion

A fine result of excision of the intradural extramedullary tumor with using surgical microscope could be acquired even in the field of orthopedic surgery.

Keywords: Intradural tumor, Microsurgical excision

Figures and Tables

Fig. 1

(A) T1-weighted sagittal MR image shows intermediate signal intensity. The tumor is located at the T10-11 level with extension of the tumor forming a dumbbell shaped mass. (B) Gadolinium enhanced T1 weighted sagittal MR image shows well contrast enhancing mass. (C) Gadolinium enhanced T1 weighted axial MR image shows a dumbbell shape intradural extramedullary mass compressing spinal cord to the left.

Fig. 2

(A) Gross section of the tumor shows well encapsulated mass measuring 2.0×1.2×1 cm. (B) The tumor is composed of spindle cells with nuclear palisading and shows vascular hyalinization (H-E stain, ×200). These findings are compatible with Schwannoma.
