Abstract
Background: Brain tumour is one of the most devastating forms of human illness especially when occurring in the posterior fossa and involving the brain stem. Posterior fossa tumours are critical brain lesions owing to limited space within posterior fossa as well as the potential involvement of vital brain stem nuclei.
Methods: It was an ambispective (retrospective as well as prospective), hospital based 10 years observational study. Patients with posterior fossa tumours were included. The various histopathological type, age, sex, clinical presentation and outcome was recorded.
Results: 546 patients of posterior fossa tumours were studied. Out of these 306 were males and 240 were females. The various types of tumours with their respective percentage is High grade Astrocytoma (27), Dermoid(12), Ependymoma (54), Epidermoid (54), Hemangioblastoma (18), Medullobalstoma (57), Meningioma( 39), Brainstem Glioma (39), Pilocytic astrocytoma(57), Schwannoma( 159), Arachnoid cyst. Hydrocephalus was present in total 327 patients (out of 546).The intra-operative and postoperative mortality was 6.77%.
Conclusions: Schwannomas are the commonest posterior fossa brain tumour in our population. Astrocytomas are most common posterior fossa tumours followed by medulloblastoma in pediatric age group.
