Large left occipital lobar haemorrhage involving cortex, subcortical white matter and periventricular white matter, and extending into the temporal lobe. There is overlying subarachnoid haemorrhage and subdural haemorrhage, plus intraventricular haemorrhage. The haematoma has multiple lobulations with finger-like projections evident (see stack key images).
Significant mass effect from the haematoma and perihaematomal oedema resulting in effacement of ipsilateral cortical sulci and the left lateral ventricle and some midline shift.
Moderate periventricular low attenuation in keeping with small vessel change +/- transependymal CSF spread. Mild atrophy.
