The key finding of hypertensive microangiopathy is the presence of microhemorrhages affecting the basal ganglia, pons and cerebellar hemispheres 1. This is, not surprisingly, the same distribution as macroscopic hypertensive intracerebral haemorrhages.

These are best seen on T2* sequences, particularly susceptibility weighted imaging (SWI) as small blooming areas of signal loss 1.

Differential diagnosis

There are a number of conditions to be considered:
