CASE REPORT
A 71-year-old man was taken to our hospital because of disordered
consciousness. His conscious level was E4V1M5 with Glasgow Coma Scale on
admission. His blood pressure was 209/124mmHg, but there was no
abnormality in both laboratory testing and cerebrospinal fluid
examination. The MRI finding reveals a high-intensity area at the pons
with FLAIR Imaging and ADC map (Fig. 1A and 1B ), but
isointensity of DWI and no evidence of the blood flow interruption.
Thus, the patient was diagnosed with PRES of the brainstem. Although his
consciousness worsened on the following day to E2V1M5, it recovered on
the 9th day with antihypertensive treatments. The patient was discharged
on the 20th day without any sequelae.
