title: Colorectal emergencies and related complications: a comprehensive imaging review--noninfectious and noninflammatory emergencies of colon.
abstract: OBJECTIVE
  In this article, we illustrate imaging findings of colorectal emergencies encountered in the acute setting that are primarily noninfectious and noninflammatory in origin. Our review should enable the reader to identify and understand common colorectal emergencies and related complications in clinical practice.
  
  
  CONCLUSIONS
  The diagnosis of colorectal emergencies is mostly straightforward, but it can be challenging because of the overlap of presenting symptoms and imaging findings. Therefore, it is essential to clarify the cause, narrow the differential diagnosis, and identify associated complications.
