What complication has occurred?
Haemorrhagic transformation of an left MCA territory infarct,
Hypodensity in the left frontal, temporal and parietal lobes is more markedly hypodense, but stable in distribution, consistent with evolution of the left MCA territory infarct. Hyperdensity within the infarct, consistent with haemorrhagic transformation, is increased in volume. Intraparenchymal haemorrhage in the inferior left temporal lobe measuring 26 x 18 mm has slightly increased from 23 x 16 mm. There is increased associated mass effect, characterised by effacement of left cerebral hemispheric sulci, partial effacement of the left lateral ventricle and 3 mm rightward midline shift at the level of the septum pellucidum. Hyperdense left MCA is again demonstrated. No new infarct detected. Old infarcts in the right caudate head and right temporal lobe, associated with ex vacuo dilatation of the occipital and temporal horns of right lateral ventricle, are again demonstrated.
