Abstract
Intracranial hemorrhage is the commonest cause of hyperdensity on the non-contrast brain CT after thrombolysis with IV-TPA. This may range from minor petechial spots within the infarcted tissue to an extensive parenchymal hematoma. We present a patient who showed considerable clinical recovery after intravenous thrombolysis for acute ischemic stroke. However, his post-thrombolysis CT scan of the brain revealed a discrete hyperdensity in the infarcted region, due to extravasation of radio-contrast injected for CT angiography. His underlying end-stage renal failure probably contributed to a reduced rate of clearance of the contrast from his body. doi:10.4021/jnr83w
