The solid abdominal viscera are secured in place by various suspensory ligaments. Laxity or incomplete development of these anchoring ligaments can lead to hypermobility 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, radiologic-pathologic correlations, and therapeutic implications of solid visceral intraabdominal torsions, including some unusual solid organ and abdominal fat torsions.
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.
各种悬韧带将实质性内脏器官固定在适当的位置。这些锚定韧带的松弛或发育不全可导致过度活动，并使患者易发生与扭转相关的缺血性病变。实质性内脏器官腹腔内扭转的临床症状不具特异性。及时诊断对于避免因长时间内脏缺血导致危及生命的后果至关重要。实质性内脏器官腹腔内扭转在临床上很少被诊断，通常需要放射科医生通过横断面成像来识别和做出诊断。本文回顾了实质性内脏器官腹腔内扭转的影像学表现、放射病理学相关性和治疗意义，包括一些不常见的实质性器官和腹部脂肪扭转。
实质性内脏器官腹腔内扭转的临床表现不具特异性，放射科医生依靠横断面成像研究来做出这一诊断。认识到腹腔内扭转的诱发因素和影像学表现对于指导对这些潜在危及生命实体的及时干预至关重要。
