Large left parieto-occipital haematoma is again demonstrated measuring 5 x 4.5 x 4 cm (AP x ML x CC; approximately 45 cc), extending into the left lateral ventricle. The degree of midline shift (9 mm to the right), left lateral ventricle effacement, surrounding reactive oedema and ipsilateral sulcal effacement is similar to the previous scan. Effacement of the right ambient and quadrigeminal cisterns suggests uncal herniation, although this has not changed in appearance compared to the earlier imaging.
