Large left frontal lobar haemorrhage involving cortex, subcortical white matter and periventricular white matter. There is subarachnoid and intraventricular haemorrhage. The haematoma has multiple finger-like projections.
Mass effect from the haematoma and perihaematomal oedema resulting in midline shift, obstructive hydrocephalus of the lateral ventricles and partial effacement of the suprasellar cistern.
Moderate periventricular low attenuation may represent small vessel change and/or transependymal CSF spread. Mild atrophy.
