摘要：The diagnosis of renal cortical abscess can be missed as thecondition is frequently associated with blood and urine culture negativity.Moreover, imaging by ultrasonography in the early stages of the disease maymiss small or developing abscesses and carbuncles. Renal abscesses being morecommon in the immunosuppressed, the condition may be overlooked in theimmunocompetent. We report a case of bilateral renal cortical abscesses in animmunocompetent individual who presented to us with Pyrexia of Unknown Origin (PUO).The patient’s urine and blood culture were negative and initial ultrasonographyof the abdomen revealed no abnormality. Based on clinical suspicion a repeatultrasonography was done, which detected bilateral renal cortical abscesses. Thus,when in doubt repeat or more sensitive imaging is required for correctdiagnosis. Important differences exist between renal cortical andcortico-medullary abscesses and this awareness guides therapeutic decision.Missing a renal cortical abscess based on single negative imaging could becatastrophic.
