Intraperitoneal abscess from perforated diverticulitis with fistualization to extraperitoneal abscess into the scrotum: a case report

Abstract

Background: Scrotal abscesses are common skin abscesses seen in the general population; however, intraperitoneal abscesses tracking into the scrotum are rare. Intraperitoneal and retroperitoneal abscesses contiguous with the scrotum have been reported in the literature in specific populations. Wound cultures can aid in differentiating the source of the infections. Recurrent abscesses have been observed in high-risk populations, such as those with malignancy or who are immunocompromised. Case presentation: We present a 71-year-old male with pericolonic abscess following perforated diverticulitis. The abscess was drained with interventional radiology and was complicated by an extraperitoneal abscess that tracked to the scrotum. Incision and drainage of the extraperitoneal abscess and the scrotal abscess were required with intravenous antibiotic therapy. The abscess tracking into the scrotum is reported without evidence of patent processus vaginalis. Conclusion: We conclude that an intraperitoneal abscess can track to the scrotum through extraperitoneal fascial planes in the absence of a patent processus vaginalis. We show that extraperitoneal abscess spread to the scrotum is possible, with wound cultures helping to differentiate the source of the infection. High-risk patients with recurrent abscesses can also be susceptible to contiguous spread.
