OBJECTIVE. The solid abdominal viscera are secured in place by various suspensory ligaments. Laxity or incomplete development of these anchoring ligaments can lead to hypermobil-ity and predispose the patient to torsion-related ischemic pathology. The clinical symptoms of solid visceral intraabdominal torsions are nonspecific. A prompt diagnosis is critical to avoid life-threatening consequences of prolonged visceral ischemia. Abdominal torsions are rarely diagnosed clinically, and it is often the responsibility of the radiologist to recognize and make the diagnosis through cross-sectional imaging. This article reviews the imaging spectrum, ra-diologic-pathologic correlations, and therapeutic implications of solid visceral intraabdominal torsions, including some unusual solid organ and abdominal fat torsions.
CONCLUSION. The clinical presentation of solid visceral intraabdominal torsion is nonspecific and radiologists are relied on to make this diagnosis on cross-sectional imaging studies. Recognition of the predisposing factors and imaging spectrum of intraabdominal torsions is essential to help direct timely intervention in these potentially life-threatening entities.
