A peripherally haemosiderin stained lesion with central high T1 and T2 signal and a small fluid level is demonstrated. There is no surrounding oedema or superficial haemosiderin staining.
A 2nd region of haemosiderin staining inferior to the head of caudate on the left is also noted without surrounding oedema.
Four punctate regions of susceptibility induced signal loss scattered throughout both hemispheres and brainstem are additionally noted.
It is worth noting that the heterogeneous signal on the phase images of SWI likely represents aliasing rather than calcification (see SWI article).
The remainder of the brain is unremarkable in appearance. Intracranial circulation is within normal limits
Conclusion:
Features are those of multiple cavernous malformations.
