Sacral osteomyelitis after abdominal hysterectomy. Early diagnosis was made difficult by the absence of neurologic findings. Such postoperative infection should be considered after pelvic surgery. Minimally invasive needle aspiration may confirm the diagnosis and reduce the necessary extent of surgical intervention ((Akhaddar A, Mahi M, Elouennass M, Niamane R, Elmoustarchid B, Boucetta M. Chronic pelvic pain reveals sacral osteomyelitis three years after abdominal hysterectomy. Surg Infect (Larchmt). 2009 Dec;10(6):549-51. doi: 10.1089/sur.2008.048. Review. PubMed PMID: 19656015. ))
