Renal Medullary and Papillary Necrosis: Impact of Early Diagnosis on Outcome

CT has emerged as the imaging modality of choice for assessment of inflammatory conditions of the kidney.1 Renal medullary necrosis (RMN) and renal papillary necrosis (RPN) occur with inflammatory renal disease, diabetes mellitus, sickle cell disease, and analgesic abuse.2-4 Multiphasic helical CT and particularly multiphasic multidetector row CT are best able to show diagnostic features of renal medullary and papillary necrosis (i.e., clefts extending from fornices into the medullary components of pyramids and poorly or nonenhancing lesions in the medulla as well as perirenal manifestations), all of which may not be demonstrable in the intravenous urogram (IVU).2 Of particular interest is the capability of multiphasic multidetector row CT to identify early manifestations of inflammatory renal lesions or those attributable to diabetes mellitus, at a stage when they are reversible with appropriate treatment.1,2,5–7 We investigated the feasibility of early diagnosis by CT of renal medullary and papillary necrosis leading to prompt treatment, and its impact on outcome.
