Abstract:
STUDY DESIGN:A retrospective study of preoperative and postoperative magnetic resonance imaging (MRI) findings in spinal ependymoma. OBJECTIVE:The goal of the study was to examine MRI features, including the syrinx component volume, after surgical resection of spinal ependymoma, and to relate these features to extent of resection and improvement of postoperative neurological status. SUMMARY OF BACKGROUND DATA:Spinal ependymomas have a variety of MRI findings preoperatively, including a hemorrhage cap sign, gadolinium enhancement, and a spinal tumor cyst. However, little is known about these features on postoperative MRI after tumor resection. MATERIALS AND METHODS:The subjects were 38 patients treated for spinal cord ependymoma of World Health Organization grade II at our hospital. All had a spinal tumor cyst on preoperative MRI. All cases were followed with MRI for >1 year after surgery, including imaging at postoperative months (POM) 1 and 12. The maximum diameter of the syrinx was measured on mid-sagittal MRI. The extent of tumor resection was categorized as gross total resection (GTR) and subtotal resection (STR). RESULTS:The mean age of the 38 patients (22 male and 16 female individuals) was 50.9 years (range, 21-71 y) at the time of surgery. The mean preoperative duration from disease onset was 14.9 months (range, 2-47 mo). GTR was achieved in 28 patients (74%) and STR in 10 (26%). The mean syrinx sizes preoperatively and at POM 1 and POM 12 were 7.5±2.3, 4.1±1.9, and 2.5±1.8 mm, respectively, with significant differences among the time points (P<0.01). The syrinx size shrunk over time after GTR and STR. The shrinkage rate was significantly higher in GTR cases (P<0.05) and in cases with the improvement of McCormick grade for neurological status after both GTR and STR (P<0.05). CONCLUSIONS:These findings suggest that MRI can be used to evaluate the improvement of neurological status after surgery for spinal ependymoma.
