Abstract: Objective To explore the main causes of misdiagnosis of acute appendicitis with secondary perirenal abscess and the measures to avoid misdiagnosis. Methods A retrospective analysis of laboratory results and surgery was made on 6 cases of acute appendicitis with secondary perirenal abscess misdiagnosed in Pingdu People’s Hospital Affiliated to Weifang Medical College. Results One case was performed laparotomy and one case was performed laparoscopy. The two cases were proved to be secondary perirenal abscess of post-cecal gangrenous appendicitis. The other 4 cases were diagnosed by multi-slice computed tomography (MSCT), one of which was improved after puncture and drainage, 1 case underwent right nephrectomy， and 2 cases died of Septicemia and multi-system organ failure due to delayed diagnosis and treatment. Conclusion The cause of misdiagnosis of acute appendicitis with secondary perirenal abscess is the nonspecific symptoms. To avoid misdiagnosis, the abdomen should be examined by MSCT.
