Non-traumatic bladder rupture (NTBR) is relative rare pathology including spontaneous rupture and iatrogenic injury. As increasing the medical intervention for the pelvic malignancy or elderly population, NTBR will be encountered more frequently. There are few previous studies summarizing the imaging features of NTBR. We reviewed imaging characteristics of 18 previous cases of NTBR experienced. In addition, 3 presentative cases that can be a pitfall to differentiate from NTBR. The aim of this article is to clarify the key CT findings of NTBR and its pitfalls.
非创伤性膀胱破裂(NTBR)是一种相对罕见的疾病,包括自发性破裂和医源性损伤。随着对盆腔恶性肿瘤或老年人群医疗干预的增加,NTBR 的发病率将会更高。目前很少有研究总结 NTBR 的影像学特征。我们回顾了 18 例 NTBR 的影像学特征,并选择了 3 个有代表性的、可能容易误诊为 NTBR 的病例。本文旨在阐明 NTBR 的关键 CT 表现及其陷阱。
