Spontaneous retroperitoneal abscess as a result of Crohn's disease does not always terminate at the psoas or iliac spaces. The abscess may continue downward breaching the obturator fascia. Passage through the sciatic foramina can result in a buttock or posterior upper thigh abscess. This possibility is illustrated in the case presented by a 40 year old female with toxemia and a fluctuant mass in the right gluteal area. Surgical drainage and control of the sepsis was followed by enterocutaneous fistula formation. Small bowel barium series demonstrated communication of the tracking abscess with the caput cecum. Surgical management consisted of formal ileocolectomy. The pathology report revealed Crohn's disease of the terminal ileum and right colon.
克罗恩病导致的自发性腹膜后脓肿并不总是局限于腰大肌或髂窝。脓肿可能会继续向下突破闭孔筋膜。穿过坐骨大孔可导致臀部或大腿上段后部脓肿。一名40岁女性出现毒血症，右侧臀区有波动感肿块，该病例就说明了这种可能性。手术引流并控制败血症后出现了肠皮肤瘘。小肠钡剂造影显示追踪性脓肿与盲肠头部相通。手术治疗包括正规的回肠结肠切除术。病理报告显示末端回肠和右结肠患有克罗恩病。
