Follow-up MRI of the brain shows:
Almost total resolution of the left lateral intraventricular haemorrhage with a resolving ill-defined area of abnormal signal intensity seen within the left caudo-thalamic groove displaying altered MR signal seen with predominantly hyperintense T1WIs and hypointense T2WIs (early subacute blood). Marked dilatation of the supra- and infratentorial ventricular system with compartmentalization of the left frontal horn.
Marked reduction of the cerebral mantle is still noted yet with reduction of the periventricular transependymal CSF permeation. A left frontal area of encephalomalacia is seen as well as irregularity of the ventricular wall.
