Guillain-Barré syndrome in a man presenting with upper extremity monoplegia.

Outside academia, community and rural medical centers often rely on clinical signs and symptoms for early intervention, as means of gathering objective data may be unavailable, or the reliance of biological testing may take too long to return. Continued reporting of atypical presentations is therefore necessary for broadening clinical recognition of such cases.

Isolated pan-pontine posterior reversible encephalopathy syndrome in a patient with uncontrolled hypertension.

Recognition of central variant PRES is key to avoiding detrimental treatment. The pons may be the most vulnerable area in central PRES, and delayed presentation may result in greater damage. CSF reporting may lead to eventual recognition of a common profile, and possible aid in future diagnosis.
