There is evidence of prior left sided craniotomy. Encephalomalacia is seen in the left frontoparietal region with coarse cortically based calcification. In addition there is a 15 mm rounded cystic region containing layering blood products in the region of the left corona radiata.
A large extra axial lesion is seen in the left parietal region measuring 54 mm across the base and 32 mm in height. There is a cystic interface between the lesion and the adjacent cortex and irregular enhancement at the base of lesion. There is moderate mass effect on the adjacent brain.
Moderate white matter disease in the periventricular white matter. Thickening of the mucosa is seen in the paranasal sinuses.
- Left parietal extra-axial lesion suspicious for a radiation induced neoplasm, most likely an unusual appearing meningioma, although other radiation induced neoplasms are not excluded.
- Haemorrhagic cystic area in the left corona radiata is noted, most likely relating to prior radiotherapy.
