Background:
The presentation of posterior reversible encephalopathy syndrome (PRES) features neuropsychiatric symptoms in the context of predominantly white matter cerebral edema in the setting of a diverse variety of underlying clinical entities.
Objective:
To illustrate the presentation and diagnostic strategy for this under-recognized condition.
Method:
We present two cases of PRES and review the available literature.
Results:
PRES may be due to a number of underlying conditions, but typically presents with symptoms consistent with delirium.
Conclusions:
Psychiatrist practicing in the general hospital should be aware of the presentation and appropriate work-up of PRES to forestall serious potential sequelae.
