title: Persistent wedge-shaped low-density lesions on computed tomography of the kidneys without infarction.
abstract: A patient with acute lymphoblastic leukemia, who developed acute renal failure, was imaged by computed tomography (CT). Persistent wedge-shaped areas of low attenuation in the kidneys were shown by sequential scans but not areas of infarction were found at autopsy. This case suggests that a wedge-shaped low-density lesion on CT may occur not only in infarcted areas, but also in areas where patchy vasoconstriction occurs.
