Abstract
The complication rate of cerebral angiography is 0.4 to 12.2% and
stroke patients are at increased risk. Non-contrast CT head done
for deterioration following angiographic procedures may show hyperdensity.
This hyperdensity usually suggests the presence of a procedure induced
hematoma. Rarely, it may be due to contrast extravasation. A high
index of suspicion is needed in the latter group of patients to
avoid unnecessary surgery. Two cases showing hyperdense lesions
on non-contrast CT following iatrogenic vascular trauma during angiography
and related procedures are presented with special emphasis on features
which help to differentiate contrast extravasation from procedure
induced hematoma.
