Psoas abscess that mimics acute appendicitis / Celerino Arroyo-Rangel ... [et al.]

Psoas abscess is rare, resulting in an under-diagnosed disease with high mortality rates. Psoitis, as psoas abscess was formerly called, can be lethal depending on how early treatment was started. The psoas abscess can simulate appendicitis and have the appendix removed without improving the condition. Symptoms are often nonspecific, leading to a delay in diagnosis. The present case developed an atypical form of psoas abscess that mimicked a case of appendicitis and underwent an unnecessary appendectomy. Laparoscopic drainage is a treatment that has advantages such as complete drainage of the abscess, short hospital stay and fast recovery.
