The multicystic elongated lesion centred in the left cingulate gyrus, with small cystic components involving the adjacent corpus callosum and frontal lobe is once again noted. There is no evidence of abnormal enhancement.
Cortical thickening and subcortical T2 signal abnormality is seen involving the right inferior frontal gyrus. There is some linear tapering towards the ventricular surface. There is no abnormal spectroscopy in this region. Normal spectroscopy. No evidence of enhancement.
1. The multicystic left cingulate region is favoured to represent a giant peri-vascular space.
2. The lesion in the right inferior frontal gyrus is favoured to represent a cortical dysplasia, possibly Taylor's type. Unfortunately, a low-grade glial series tumour cannot be totally excluded.
