title: Pheochromocytoma presenting as exacerbation of post traumatic stress disorder symptomology.
abstract: OBJECTIVE
  The following case report and discussion is intended to increase awareness of the difficulties in diagnosing pheochromocytoma when a primary psychiatric diagnosis is first suspected.
  
  
  METHODS
  The case of a middle-aged combat veteran who was admitted with agitation and flashbacks is presented. Episodes of hypertension were initially believed to be related to agitation or alcohol withdrawal. When the hypertensive episodes persisted, further evaluation revealed a pheochromocytoma. In three years' follow-up since removal of the tumor, the patient has shown considerable improvement in the symptoms of Post Traumatic Stress Disorder (PTSD).
  
  
  CONCLUSIONS
  Pheochromocytoma should be considered in patients with psychiatric disorders if a pattern of hypertensive episodes persists or worsens. The case highlights the importance of medical evaluation in patients presenting with psychiatric complaints.
