Background: T
he management of intracranial and spinal tumours remains a daunting task with the dearth of neurosurgeons in Nigeria. These tumours are believed to be rare and so, usually not suspected, and most often than not, go undiagnosed. With the increasing availability of modern radio-diagnostic facilities and great benefits of early diagnosis, the index of suspicion of medical practitioners for these tumours in the developing countries need to be raised.
Objective: The study is aimed at determining the demographic and pathologic profiles of neurosurgical tumours involving the cranium and spine in Zaria, North-West Zone of Nigeria.
Methodology: A 9-year retrospective study of patients managed for cranial and spinal tumours 2007-2015 was conducted at the Ahmadu Bello University Teaching Hospital, ABUTH, Zaria, Kaduna State, Nigeria. The hospital is a tertiary health institution and major referral centre in the northern part of Nigeria. The ward records, operation theatre logbooks, and Histopathology department records were used for data collection. The paediatric age group was taken as =16years, and only patients with histological confirmation had their data included and analyzed, using SPSS version 21.
Results: There were 125 histologically diagnosed tumour cases, and age range was 2-80years, with a mean of 31.5years (SD 16.5). Sixty-six patients (52.8%) were males, giving a M:F ratio of 1.1:1, while 26 (21.7%) were in the paediatric age group, =16years. Cranial tumours constituted 88%, giving a cranial to spinal tumour ratio of 7.3:1, and the most common tumour was meningioma (44%). There was a significant association between histological diagnosis and sex (p=0.011).The most common neurosurgical tumour among the paediatric age group were gliomas (30.8%), and there was no metastatic tumour diagnosed in the paediatric group. Meningioma was the most common spinal tumour (46.6%), followed by metastatic spinal tumours (20%).
Conclusion: There appears to be an upsurge in the incidence of these tumours, in our study, with an overall slight male preponderance, and the most common tumours were meningioma, glioma and pituitary adenoma. In patients aged =16years, glioma, meningioma and medulloblastoma were the most common tumours. Gliomas are as common in males as meningiomas are in females.
