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.
