Mass effect involves the hippocampal head, amygdala, adjacent portion of the anterior temporal lobe, with the thin section axial T2 scans and the previous coronal T2 scans demonstrating a micro cystic appearance. The lesion is centred on grey matter with some extension into the white matter. There is no abnormal contrast enhancement. No vasogenic oedema extends beyond the lesion. The left cerebral hemisphere is normal.
