MRI
Predominantly left parietal convexity extraaxial mass (CSF cleft sign) with a cystic component that appears intra-axial and left frontoparietal vasogenic oedema. ADC values are low (745 10-6 mm2/s). There is SWI signal abnormality corresponding to the areas of calcification on CT. The mass is avidly enhancing with evidence of parenchymal enhancement suggestive of brain invasion - this is best appreciated on the coronal and sagittal imaging.
