Right parietal craniotomy and evacuation of the right temporoparietal haematoma with evacuation of much of the haematoma. There is persistent gyral swelling and sulcal effacement throughout the right temporal, parietal and occipital lobes with mild compression of the right lateral ventricle but no midline shift. Foci of deep and periventricular white matter hyperintensity likely represents chronic small vessel ischaemic change.
Poorly seen due to motion degradation, are a number of small punctate regions of signal drop out on EPI suggestive of microhaemorrhages. They are peripeheral in distribution.
No enhancing lesion seen within the region of the haematoma. The overlying dura is slightly thickened and enhancing in keeping with the recent postoperative state.
MRA (not shown) demonstrates no malformation, aneurysm, stenosis or other vascular abnormality.
Location and presence of microhaemorrhages suggests a lobar haemorrhage secondary to cerebral amyloid angiopathy.
