Background/aims: Intracranial tumours demonstrate characteristic diagnostic histopathological features. Our aims were to look at the histo-pathological pattern of intracranial tumours in our environment including their age and sex distribution.
Methods: The histology request forms and slides of all intracranial specimens submitted to the histo-pathology department of National Hospital, Abuja, over an 11 year period (2005 and 2015) were retrospectively reviewed.
Results: Intracranial specimens and intracranial tumours accounted for 0.6% and 0.5% respectively of all samples submitted. Meningiomas accounted for the most frequent diagnosis for all intracranial specimens and intracranial tumours at 35% and 41% respectively followed by pituitary adenoma at 19% and 22%, and astrocytoma at 13% and 20%. The male female ratio for all diagnoses was 1:1. The mean age at diagnosis was 35 ± 17.1 years. The frequency of intracranial tumours in children was 11.8% with a mean age of 8.3 ± 4.4 years and an equal sex distribution. In children, glioma and embryonal tumours were the most frequent diagnosis at 25%.
Conclusion: The histo-pathological pattern of intracranial tumours in our environment showed that meningioma is the most common intracranial tumour in adults, while glioma and embryonal tumours are the most common intracranial tumours in children.

Keywords: Histo-pathological pattern, intracranial tumour, meningioma, glioma, embryonal tumours.
