Abstract
BACKGROUND: Meningiomas are the second commonest intracranial tumours in many places worldwide. It is however rare in the paediatric age group and most studies have been able to document only a few patients. Meningiomas in paediatric patients have also being shown to behave differently to those in the adult population. This study was done to examine histological types of meningiomas seen in paediatric patients from a predominantly African population using the 2016 WHO grading system for intracranial tumours.
METHODS: Data from the operating logs of patients and histology reports of the samples sent to the Pathology department during the study period were extracted. The data obtained include the age, sex, location of the intracranial tumour, histologic diagnosis, WHO grade and tumour recurrence.
RESULT: A total of 9 paediatric age patients were found among the 166 surgically excised meningiomas received at the department of Pathology in our institution over a nineteen-year period. The age range was from eight months to seventeen years. There was a male to female ratio of 1:2 with a female predominance. Six of the tumours were basally located. All the tumours were WHO grade I with transitional meningiomas being the commonest followed by meningothelial. There was no history of recurrence in any of the tumours following complete surgical excisions.
CONCLUSION: Our study showed rarity of the meningiomas in the study population and there was a predominance of basally located tumours.
