Results
:Of the 24 patients (12 male,
12 female; mean age 49.5 ± 18.1 years,
range: 19-74years)),
13 patients showed intramedullary tumors,
9 Patients presented extramedullary intradural tumors and2 patients had epidural masses.
6 patients had ependymomas,
5 Patients showed meningiomas,
3 patients had cavernomas,
1 patient showed a cord oligodendroglioma,
another a LGG,
1 patient had a cord Glioblastoma.
1 patient had a chordoma with mass effect on the spinal cord.
One patient presented with an intramedullary Hemangioblastoma,
1 Patient showed an intradural extramedullary Neurinoma and of 1 Patient no histology was available but images suspected a hemangioblastoma of the spinal cord.
2 Patients showed Metastasis (one of an angioinvasive atypical carcinoid of the lung and one of an osteosarkoma . One lesion was proven to be an epidural abscess due to spondylodiscitis with massive compression of the spinal cord.
The lesions could be classified into 3 types according to the fiber course.
In Type 1 (10 cases)(Fig.
1) fibers did not pass through the lesion.
In Type 2 (5 cases) (Fig.2 )some fibers crossed the lesion,
but most of the lesion volume did not contain fibers.
In Type 3 (9 cases)(Fig.
3) the fibers were completely encased by tumor.
Based on these results,
13 tumors were considered resectable,
11 were not.
