Acute lobar nephronia (ALN) refers to a renal mass caused by acute focal infection without liquefaction. The radiological findings in 12 patients with 13 episodes of ALN are described. A characteristic combination of uroradiological findings is (a) a relatively sonolucent mass which disrupts corticomedullary definition on ultrasonography; (b) a solid-appearing mass on other uroradiological studies; and (c) a positive gallium image in the region of the mass, which may be associated with increased activity elsewhere in the same or opposite kidney. The angiographic finding of significant venous narrowing within the mass associated with only minor arteriographic abnormalities is characteristic of ALN as well.
急性大叶性肾周炎（ALN）是指由急性局灶性感染引起的无液化的肾肿块。本文描述了12例患者13次发作的ALN的放射学表现。尿放射学表现的特征性组合为：（a）超声检查显示相对无回声的肿块，破坏皮质髓质界限；（b）其他尿放射学检查显示肿块呈实性；（c）肿块区域镓显像阳性，可能与同侧或对侧肾脏其他部位活性增加有关。肿块内明显静脉狭窄而动脉造影仅有轻微异常的血管造影表现也是ALN的特征。
