頻回のCTガイド下経皮的ドレナージを要したS状結腸瘻孔形成による腸腰筋膿瘍の1例

A case of iliopsoas abscess due to sigmoid colon fistula formation requiring frequent CT-guided subcutaneous drainage

消化器疾患と関連した腸腰筋膿瘍において，S状結腸の穿孔を原因とするものは比較的まれであるとの報告がある。今回，異物のS状結腸穿孔によって腸腰筋膿瘍を発症したと考えられる症例を経験したので若干の文献的考察を加えて報告する。

A 76-years old man visited our hospital for the purpose of scrutiny of cerebral infarction.

CT was carried out because he had a fever at the time of examination, and he was diagnosed as a right iliopsoas abscess. Three times in total CT-guided drainage was performed, but the sympyom did not improve. After all, it was diagnosed as a iliopsoas abscess by intestinal perforation by fistula imaging. Sigmoid colon fistula suture closure was performed, and the symptom was improved. It was found that iliopsoas abscesses, which are ineffective in the treatment of drainage and antibiotic, may develop abscesses due to fistula formation with the digestive tract.
