Abstract:
The spot sign refers to tiny enhanced foci within the hematoma on a brain computed tomography angiography image. A spot sign is usually considered to be associated with hematoma progression in patients with acute intracerebral hemorrhage. We describe a patient with infarction of the left middle cerebral artery where a spot sign was observed. A spot sign may also have significant predictive value for large hemorrhagic transformation in patients with ischemic stroke.
