title: Pulsatile tinnitus as the presenting symptom in a patient with posterior reversible encephalopathy syndrome.
abstract: OBJECTIVE
  We present a case of posterior reversible encephalopathy syndrome (PRES) presenting with pulsatile tinnitus. We highlight the significance of a detailed neurological and cardiovascular assessment including the measurement of blood pressure in patients presenting with pulsatile tinnitus.
  
  
  METHODS
  Case presentation and literature review.
  
  
  RESULTS
  One patient with undiagnosed PRES, who presented to our ear, nose and throat surgery department with pulsatile tinnitus is discussed. Symptoms, signs, investigations and treatments are presented. A literature review is also included.
  
  
  CONCLUSIONS
  Pulsatile tinnitus can be the presenting symptom of neurovascular disorders, some of which might have serious sequelae if not treated promptly. Detailed neurological and cardiovascular history is recommended in addition to radiological investigations in patients presenting with pulsatile tinnitus.
