A left parieto-occipital craniotomy has been performed and approximately the lateral two thirds of the left posterior temporal tumour has been resected, leaving a fluid filled cavity. The surgical tract crosses the left occipital white matter and is filled with haematoma intensity material. Post contrast views show continued enhancement of the medial and inferior aspect of the tumour. Thin linear enhancement around the periphery of the fluid filled cavity may represent only post operative change at this stage. The lesion in relation to the left cerebral peduncle is unchanged. Slight increase in the extent of vasogenic oedema within the left parietal and occipital lobes.
