Abstract
|
|
|
|
Despite the wide availability of brain magnetic resonance imaging, computed tomography (CT) still remains the imaging modality of choice in acute ischemic stroke. Hyperdense artery sign is the earliest indicator of intracranial occluding clots on non-enhanced brain CT, and has been associated with poor clinical outcomes. While hyperdense middle cerebral artery signs are frequently mentioned, hyperdense anterior cerebral artery (ACA) signs have rarely been reported, especially in the sagittal plane. This study demonstrates a case of hyperdense ACA sign identified on sagittal brain CT followed by successful intravenous thrombolysis.
