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.
一名患有急性淋巴细胞白血病并发展为急性肾衰竭的患者接受了计算机断层扫描（CT）检查。连续扫描显示肾脏存在持续的楔形低密度区域，但尸检未发现梗死区域。该病例表明，CT上的楔形低密度病变不仅可能出现在梗死区域，也可能出现在发生局部血管收缩的区域。
