Spontaneous rupture of the inferior vena cava (IVC) is a rare entity. We report a case of a spontaneous IVC rupture associated with IVC filter thrombosis in a patient presenting with severe atraumatic back pain. Computed tomography (CT) identified a retroperitoneal hematoma and suggested IVC thrombosis. Magnetic resonance (MR) imaging confirmed the presence of IVC filter thrombosis and demonstrated a large defect in the infrarenal IVC, with the vessel lumen in free communication with the adjacent hematoma. The patient was managed conservatively and discharged in stable condition. MR imaging played an important role in characterizing the CT findings, which were unclear.
下腔静脉(IVC)自发性破裂是一种罕见的情况。我们报告一例在出现严重非创伤性背痛的患者中,下腔静脉自发性破裂合并下腔静脉滤器血栓形成的病例。计算机断层扫描(CT)发现腹膜后血肿并提示下腔静脉血栓形成。磁共振(MR)成像证实了下腔静脉滤器血栓形成的存在,并显示肾下下腔静脉有一个大的缺损,血管腔与相邻的血肿相通。该患者接受了保守治疗,出院时病情稳定。MR成像在明确CT检查不清晰的结果方面发挥了重要作用。
