Prior Study
CT HeadNegative noncontrast CT
MR T1-w post contrast exam
Subtle evidence of hyperemia along the left parahippocampal gyrus consistent with recent seizure activity.
T2-w MR
Evidence of recent (i.e. acute phase), but not hyperacute bilateral hippocampal post seizure injuries. Changes are more obvious on the left than the right and the findings are mainly centered in the posterior body and tail of both hippocampi. The subtlety of the findings could reflect a very limited post seizure injury or post seizure events being ofset in their timeframe. Currently, both sides are in the later acute to subacute phase, based on the fading hyperintense edema and the reappearance of the myelinated tracts, especially on the right.
