Case Discussion
Case of an acute MCA territory infarct with a hyperdense MCA sign.
The hyperdense MCA sign is seen on non-contrast CT as a focal hyperdensity of the middle cerebral artery (MCA) and corresponds to the direct visualization of thromboembolic material within the lumen. It considered the earliest visible sign of MCA infarction.
