Abstract

Spinal meningiomas are relatively rare tumours with often favourable surgical outcomes. There is paucity of data on spinal meningiomas in the Nigerian literature. This study was designed to evaluate the incidence, the anatomical distribution and outcome of surgical treatment of spinal meningiomas in our center. This was a retrospective study of patients who had surgery for spinal meningioma at our center during the study period. We obtain data from case note, operation and pathology registers. Univariate analysis was performed using SPSS version 15 (SPSS Science Inc; Chicago, IL, USA). There were 11 patients in the study all of whom were females with age range of 26-65 years. All the patients had motor deficit at presentation. Four patients (36.4%) presented within 6 months of onset of symptoms while the duration of symptoms was more than a year in 5 patients (45.5%). The preoperative functional grading was Frankel A in 2 patients (18.2%), Frankel D in 1 patient (9.1%), Frankel B and C each in 4 patients (36.4%). The tumours were located in the thoracic region in six patients (54.5%), cervical region in 2 patients (18.2%) while the tumours were cervicothoracic in the other 3 patients (27.3%). All the patients had gross total tumour resection. Post-operative neurological improvement occurred in 7 patients (63.6%) while 4 patients (36.4%) remained neurologically the same. All the patients in this study were women. Gross total tumour resection was achieved in all the cases with satisfactory functional outcome.
