A new right sub dural haematoma is demonstrated, with acute on chronic features and blood products layering dependently. This measures approximately 10 mm in maximum diameter and results in mild mass effect on the fronto parietal parenchyma. No significant midline shift.
Previous left occipital craniotomy. Encephalomalacia, with haemosiderin staining within the left occipital lobe, with adjacent associated FLAIR signal in region of previous haematoma. Superficial siderosis as demonstrated on susceptibility imaging seen in the parieto-occipital regions and spires in the right frontal lobe, consistent with previous haemorrhage.
In addition to this, numerous bilateral punctate peripheral foci of susceptibility change are consistent with micro haemorrhages related to amyloid angiopathy.
