XXXX caused by @entity698 : a case report.

@entity1 @entity32 @entity697 @entity295 @entity698 @entity2466 @entity39 @entity881 @entity490 @entity158
@entity697 is one of the most common causes of acute @entity490 . Accurate diagnosis is often hindered due to various presentations that differ from the typical signs of @entity698 , especially the position of the appendix. A delay in diagnosis or treatment may result in increased risks of complications, such as perforation, which is associated with increased morbidity and mortality rates. @entity39 caused by @entity698 is extremely rare. We herein report a case of 50-year-old @entity1 presenting with an @entity2466 in local hospital. After ten days of conservative treatment with intravenous antibiotics, the @entity1 complained about @entity158 and swelling of the right lower limb and computed tomography (CT) demonstrated a @entity2466 and gas and fluid collection extending from his retroperitoneal cavity to the subcutaneous layer of his right loin and right lower limb. He was transferred to our hospital and was diagnosed with @entity39 caused by @entity698 . Emergency surgery including surgical debridement and appendectomy was performed. However, the @entity1 died of severe @entity295 and @entity881 two days after the operation. This case represents an unusual complication of a common disease and we should bear in mind that retroperitoneal @entity32 and/or abscesses may cause @entity39 through lumbar triangles.
