Letter to the Editor

Sir,

Renal papillary necrosis is a well-described entity on intravenous pyelogram (IVP) and CT urogram in both the adult and pediatric populations [1, 2, 3]. However pediatric renal papillary necrosis is less frequently encountered, particularly on magnetic resonance urogram [4, 5, 6]. Indeed, to the best of our knowledge renal papillary necrosis has yet to be described on MR urogram. We present a case of renal papillary necrosis demonstrated by MR urogram in a child with previously undiagnosed sickle cell trait.

A 17-year-old previously healthy African-American girl presented to our institution with a 3-day history of gross hematuria. Her medical history was unremarkable except for recent streptococcal pharyngitis. After 2 months of extensive and inconclusive evaluation, including laboratory analysis, renal US, and a renal biopsy, the hematuria persisted, with hemoglobin decreasing to 4 g/deciliter. The girl was subsequently evaluated by cystoscopy, which demonstrated hemorrhage from...
