Hyperacute Seizure 01 - Clinical Case Summary
SummaryHistory
17 yo female with episode of 5 seconds of an out of body experience, then tilting of vision, general distress, and dizziness (could not walk straight) lasting about 1 hour.
Exams Performed
MR T1-w post contrast only; MR Coronal T2-w spin echo and MR FLAIR; MR diffusion
Prior available imaging reports
CT Head not available
T1-w MR post contrast
1. Negative Post contrast T1 weighted MR without focal abnormaliy to account for recent seizure.
T2-w coronal & Flair
1. Abnormal changes are evident in the body and tail of the left hippocampus consistent with a recent (hyperacute or early acute phase) seizure.
2. No foreign tissue lesions are evident
MR Diffusion (DWI)
1. The MR diffusion (DWI) sequence demonstrates some shine-through T2-w hyperintensity. No ADC map is available to assess for positive water restriction.
MR Susceptibility (SWI) not available

MR Susceptibility (SWI) not available
Overall impression
1. Edema and effacement of the internal and external white matter tracts within the left hippocampus consistent with hyperacute post seizure changes. No other abnormalities are evident.
Lessons to be Learned
Acute seizure activity is often, as in this case, segmental within parts of the hippocampus. Thus, a careful search is necessary of all parts of the hippocampus individually.
