Subdural haemorrhage - acute with active bleeding

Case contributed by A.Prof Frank Gaillard


Head injury

CT of the brain demonstrates a large acute subdural haemorrhage with associated extensive cerebral contusions and a large scalp haematoma on the left, in keeping with a coup-contrecoup injury pattern. 

CTA demonstrates a globular blush of contrast representing active extravasation of blood into the subdural haemorrhage.

Case Discussion


It is always important to remember that CT is a snapshot of a potentially dynamic process, and the size of a haemorrhage at the time of the scan does not mean that it will not continue to enlarge. Presence of a spot sign in parenchymal haemorrhages has been well described, however, identical findings will be seen anywhere that active bleeding is occurring.
