Retroperitoneal abscess is a rare condition and is usually secondary to underlying morbidity such as diabetes, previous surgery, cirrhosis, open or closed trauma, diverticulitis, appendicitis, renal tumour and immunosuppression.
A 44 year old man without previous pathology presented with a retroperitoneal abscess. The C-reactive protein and leukocyte levels were elevated. The diagnosis was made by abdominal tomography.
The patient was treated with imipenem and surgical drainage. Twelve months later the patient was asymptomatic.
Retroperitoneal abscess in healthy patient is a very uncommon condition. The pathology should be considered in a patient who presents with abdominal pain, fever and raised analytics. The treatment should be by drainage and antibiotic therapy.
