Hyperdense MCA sign

Case contributed by A.Prof Frank Gaillard


Acute dysphasia and facial droop.

Patient Data

Age: 75 years
Gender: Male

CT brain

Non-contrast CT demonstrates a hyperdense MCA artery, extending into the sylvian fissure and seen as a hyperdense dot on axial imaging (dot sign). No evidence of a definite established infarct although patchy regions of the insula cortex appear ill-defined. 

Case Discussion

This case demonstrates the typical appearance of a hyperdense MCA sign, not in the M1 segment, but more distally in M2 and M3 branches. It thus appears as a dot in axial images.
