Gyriform hyperdensity in the infarct territory represents petechial hemorrhagic infarction and fogging.
Numerous linear and punctate foci of hemorrhagic transformation.
Case Discussion
This case exemplifies, in the same patient, the appearance of
- acute MCA territory infarct with MCA dot sign
- subacute MCA infarct with laminar necrosis
- eventual hemorrhagic transformation thereof
