A punctate focus of abnormal susceptibility within the anterior right frontal deep white matter demonstrates is difficult to identify on T1 and T2 weighted sequences and does not have surrounding vasogenic oedema.
On phase images it demonstrates both black and white areas; the central areas is artefactually low due to aliasing whereas the superior and inferior dipoles correctly identify this lesion as being composed of blood product.
Multiple punctate high T2 FLAIR foci within the supratentorial periventricular deep white matter are non-specific, but possibly secondary to chronic ischaemic microangiopathy.
