title: Live conjoined twins: a rare first trimester diagnosis during emergency department sonography.
abstract: BACKGROUND
  The evaluation of vaginal bleeding and pelvic pain in the first trimester of pregnancy is an important component of emergency physician training. The increased use of bedside sonography by emergency physicians in the evaluation of these patients requires knowledge about the normal anatomy, variants, abnormal findings and their appearance on sonography.
  
  
  OBJECTIVE
  To highlight the importance of a thorough pelvic and abdominal sonographic examination during a routine evaluation in the emergency department (ED).
  
  
  METHODS
  We present the case of a patient found to have conjoined twins diagnosed by ED sonography.
  
  
  CONCLUSIONS
  A discussion of the diagnosis, the findings on bedside sonogram and management options are presented.
