“…Several predisposing factors have been identified in the literature and these include trauma, hypertension, anticoagulation therapy, Valsalva manoeuvre and pregnancy/post-partum [14][15][16][17][18][19][20]. The mechanisms causing haemorrhage in meningioma are still not fully understood; however many hypotheses have been proposed:…”

Haemorrhage in intracranial tumours is usually associated with malignant primary brain tumours or metastases and rarely with grade 1 meningiomas. We present the case of a 64-year-old woman, who presented acutely and was found to have a convexity meningioma with intratumoral and subdural haemorrhage. A review of the literature has been performed to look at all published cases of meningiomas with haemorrhages, particularly in relation to their subtypes.The association of meningiomas with different types of intracranial haemorrhage has been discussed. Various factors potentially responsible for haemorrhage and association with subtypes has also been discussed. Review of Literature Meningiomas are slow-growing, extra-axial tumours which arise from the arachnoid cap cells in the meninges [1]. They are the commonest benign intracranial tumour and they constitute about 20% of all primary intracranial tumours [1-3]. Meningiomas are classified
