Elderly patient ~6 hours following right carotid endarterectomy developed left-sided weakness.
The right hemisphere demonstrates swollen hyperdense cortex with positive mass effect. No hemorrhage.
12 hours later
CT scan obtained 12 hours later demonstrates reduced swelling and mass-effect.
36 hours later
Repeat CT 36 hours later demonstrates almost complete resolution of findings with no evidence of an underlying stroke.
52 hours later
Yet another repeat study on the third day following carotid endarterectomy demonstrates continued resolution, with at most only minor residual swelling of the right temporal lobe.
