Recurrent Occipital Seizures with Transient MRI Changes

Figure 2

Axial brain MRI images of the patient showing transient left occipital enhancement following episode of clustered seizures in 2013 (a, b, c, d) and in 2017 (e, f, g, h). In 2013, (a) peri-ictal brain MRI-DWI shows diffusion restriction in left occipital cortex one day after her first reported seizure. (b) Follow-up MRI-DWI five weeks later shows complete resolution of abnormality in left occipital cortex. (c) Peri-ictal brain MRI T2/FLAIR shows hyperintense signal in left occipital cortex one day after her first reported seizure. (d) Follow-up MRI T2/FLAIR five weeks after seizure activity shows complete resolution of abnormality in left occipital cortex. In 2017, (e) peri-ictal brain MRI-DWI shows diffusion restriction in left occipital cortex one day after her first reported seizure. (f) Peri-ictal ADC map shows hypointensity in the left occipital cortex. (g) Peri-ictal brain MRI T2/FLAIR shows hyperintense signal in left occipital cortex. (h) Follow-up MRI T2/FLAIR six weeks following seizure activity shows complete resolution of abnormality in left occipital cortex.
