Left frontal lobe spherical mass (3 cm) with massive perifocal oedema, moderate regional mass effect with effacement of the frontal sulci and left lateral ventricle.
The mass shows a concentric target sign in several measurements, best seen in the T2w TSE.
Peripheral closed ring enhancement.
SWI shows concentric susceptibility (microhemorrhages or calcifications).
Separate Focal T2-hyperintensity in the right lentiform nucleus might be a small separate lesion.
