We report the magnetic resonance imaging (MRI) findings in 2 patients with multilocular cystic nephromas. Both underwent MRI immediately prior to resection. The images accurately reflected the morphology of the tumors: in each, the capsule was hypointense on all pulse sequences. Varied intensities of signal from the fluid in the visualized locules presumably represented differing concentrations of old hemorrhage and protein. In one case soft tissue elements became hyperintense on T2-weighted images. We speculate that MRI of multilocular cystic nephromas will produce imaging features that are highly suggestive, but not always pathognomonic, of the disease.
我们报告了2例多房性囊性肾瘤患者的磁共振成像（MRI）结果。两名患者在切除术前均立即接受了MRI检查。图像准确反映了肿瘤的形态：在每例中，包膜在所有脉冲序列上均呈低信号。可见小房内液体的信号强度各异，推测代表不同浓度的陈旧性出血和蛋白质。在1例中，软组织成分在T2加权图像上呈高信号。我们推测，多房性囊性肾瘤的MRI将产生高度提示该病的影像学特征，但并非总是具有确诊意义。
