title: Unusual radiographic presentation of IgA nephropathy.
abstract: An adolescent male presented with hematuria and flank pain. Transient focal renal parenchymal defects were demonstrated by ultrasonography, radionuclide scintigraphy and computed tomography. Renal biopsy revealed IgA nephropathy with acute tubular necrosis. This peculiar radiographic pattern has not, to our knowledge, been previously described in IgA nephropathy and may relate to tubule cell damage by red blood cell casts or patchy renal ischemia.
