A Pressing Emergency in Oncology: A Case Series of Patients With Posterior Reversible Encephalopathy Syndrome

Posterior reversible encephalopathy syndrome is a neurological emergency that may evade the discerning attention of the attending physician. Owing to the extensive range of clinical features and MRI findings, the list of differential diagnoses is substantial. The reversibility of symptoms, while not always applicable, is predominantly certain, as demonstrated in our case series. We must extend our focus beyond conventional risk variables such as hypertension to consider additional clinical insults. Delayed diagnosis may lead to worse neurological outcomes.
