Acute segmental renal infarction: Difficulty in diagnosis despite multimodality approach

The radiographic features of an acute segmental renal infarct are described as determined by intravenous urography, retrograde pyelography, ultrasonography, computed tomography, and radionuclide renography. Despite the combined approach, the radiographic features alone were not sufficiently distinctive to permit preoperative diagnosis. The limitations of these radiographic modalities are discussed with respect to differentiating an acute segmental renal infarct from other hypovascular infiltrating renal lesions.
