Twist in the Bowel: A Multimodality Radiological Imaging Spectrum

Volvulus affecting the gastrointestinal (GI) tract is one of the common causes of recurrent pain in the abdomen, and often, patients present with non-specific abdominal pain associated with nausea and/or vomiting. A high degree of suspicion is required at the clinician's end to suspect this diagnosis, which is usually confirmed by imaging using radiographs, fluoroscopic evaluation, and computed tomography. Familiarity of the clinician and radiologist with the imaging appearances of these emergent conditions on various imaging modalities is quintessential to avoiding life-threatening complications like bowel ischemia or perforation, which are associated with delayed or missed diagnosis. Our article describes the clinical features and classical imaging of the various types of volvulus affecting different bowel segments in the entire GI tract.
