title: Bedside emergency ultrasound in a case of acute parotid duct sialolithiasis.
abstract: BACKGROUND
  Sialolithiasis with salivary gland obstruction can mimic more frequently occurring illnesses such as facial and dental infection and abscess. It is often difficult to discern the etiology of facial pain and swelling on physical examination alone, requiring advanced imaging in the emergency department.
  
  
  METHODS
  We describe the case of a 37-year-old man who presented with 5 days of worsening unilateral facial pain and swelling. Use of bedside emergency ultrasound by an emergency physician (EP) led to an appropriate diagnosis of parotid duct sialolithiasis. Why Should an Emergency Physician Be Aware of This? Use of bedside emergency ultrasound performed by a trained EP successfully diagnosed symptomatic sialolithiasis of the parotid duct in the emergency department without the need for computed tomography. The utility of bedside emergency ultrasound in the evaluation of sialolithiasis and the outcomes of our case are discussed here.
