Spontaneous Retroperitoneal Methicillin-Resistant Staphylococcus aureus Abscess in a Pediatric Patient

Cureus. 2021 Jul 2;13(7):e16111. doi: 10.7759/cureus.16111. eCollection 2021 Jul.


Retroperitoneal abscesses are relatively uncommon in infants and children. They carry a high rate of morbidity due to insidious onset and pose a diagnostic challenge. Here we report a case of spontaneous retroperitoneal methicillin-resistant Staphylococcus aureus (MRSA) infection in a two-year-old patient. The patient was successfully treated with antibiotics and surgical washout and drainage. A retroperitoneal abscess is usually found in patients with a history of osteomyelitis, seeding of post-traumatic pelvic hematomas, post radiation, or perforated hollow viscus including but not limited to: perforated appendicitis, bowel perforations due to foreign objects or malignancy, or perforated diverticulitis. Most of these conditions are usually found in the adult population. As per a recent literature search, there are no reported cases of a spontaneous retroperitoneal MRSA abscess in the pediatric population without risk factors.
