Non-contrast CT (A) performed demonstrates a small right basal ganglia intracerebral haemorrhage. CTA source image demonstrates punctate focus of contrast enhancement within the haemorrhage that was discontinuous from adjacent vessels on multi-planar reformats, and not present on the pre-contrast image, the CTA 'spot sign', reflecting active, dynamic haemorrhage. Follow-up 24 hour non-contrast CT (C) demonstrates haematoma growth.
