Hyperdense MCA Sign

The hyperdense MCA sign refers to high attenuation of a segment of the MCA located in the Sylvian fissure indicating presence of a thromboembolus.  The images again demonstrate a dense right MCA with territorial infarction.

    Another great case. Thanks for posting. Just a small typo: It should say...right MCA.

    All the best,
