Large hyperdense intracerebral haematoma seen involving the left temporo-occipital region, measuring approximately 8.7 x 3.8 x 4.5 cm (AP x TR x CC) (about 75 cc), with surrounding hypodense oedema. Associated positive mass-effect, with effacement of the adjacent cortical sulci, compression of the left lateral ventricle, right-sided midline shift/subfalcine herniation, and probable early left uncal herniation. A swirl sign is noted within the haematoma possibly suggestive of active bleeding and predictive of haematoma expansion.
Further workup including CT cerebral angiography and MRI is recommended to detect the underlying cause.
