Fatal Retroperitoneal Bleeding Caused by Metastasis of a Sigmoid Carcinoma

الملخص EN

Retroperitoneal bleeding is relatively rare and a potentially life-threatening condition with significant mortality.

Early recognition requires a high index of suspicion.

Increased life expectancy, the widespread use of anticoagulants, and the rise of endovascular interventions have caused an increase in the incidence of retroperitoneal bleeding.

We present a case of a 74-year-old woman who died because of retroperitoneal bleeding caused by retroperitoneal metastasis of a sigmoid carcinoma with angioinvasive growth into a lumbar artery.

In addition we discuss etiology, diagnostic management, and treatment strategy.
