The studies demonstrated significant potential of AS as a useful delineation tool in contouring target volumes and OARs in head and neck cancers. However, it is evident that AS cannot totally replace manual delineation in contouring some structures in the head and neck and cannot be used independently without human intervention. It is also emphasized that delineation studies should be conducted locally so as to evaluate the true value of AS in head and neck cancers in a specific center.

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
