Posterior reversible encephalophaty syndrome

Case contributed by Professor Ali Hekmatnia

Presentation

Eclampsia and postpartum seizure.

Patient Data

Age: 35 years
Gender: Female

There are bilateral asymmetrical nonrestricted T2/FLAIR high signal intensity within the cortex and subcortical region of both parietal and occipital and frontal lobes and right external capsule and lentiform nucleus. ADC signal is increased in affected regions due to increased diffusion.

Case Discussion

Asymmetric expression and basal ganglia and external capsule involvement in PRES are not common. Partial or asymmetric PRES is more frequently recognized in patients with eclampsia and solid organ transplantation. Awareness of this variability in the pattern is important in proper recognition of PRES, when present.
