Abstract

While the presence of incidental breast and lung masses on cardiac scans is well known, renal masses are often incidentally discovered as well on cardiac examinations, some of which are malignant. We searched the electronic medical record system over the past 18 years, since the system was installed, for patients with a cardiac rubidium-82 (82Rb) rubidium PET/CT or technetium-99m (99mTc) sestamibi SPECT/CT performed within 1 year of a renal-protocol CT or MR. Each PET/CT or SPECT/CT was examined for presence of a renal lesion on the attenuation-correction CT images. We found 43 SPECT/CT and 18 PET/CT studies which fit the desired criteria. Of these, 7 SPECT/CT studies and 2 PET/CT studies demonstrated the renal mass on at least one of the two sets of CT images (rest or stress); if not visible, most commonly the tumor was either out of the field of view or had already been removed. Of these, 6 SPECT/CT and 2 PET/CT studies demonstrated a malignancy. Cardiac SPECT/CT and PET/CT images demonstrate incidental renal masses with a non-negligible frequency, and CT images should be carefully examined.

SPECT/CT和PET/CT上偶发肾肿块。
虽然在心脏扫描中偶然发现乳房和肺部肿块是众所周知的,但在心脏检查中也经常偶然发现肾脏肿块,其中一些是恶性的。自该系统安装以来,我们检索了过去18年的电子病历系统,以查找在肾脏协议CT或mr后1年内进行心脏铷-82 (82Rb)铷PET/CT或锝-99m (99mTc) sestamibi SPECT/CT的患者,每个PET/CT或SPECT/CT在衰减校正CT图像上是否存在肾脏病变。我们发现43个SPECT/CT和18个PET/CT研究符合预期标准。其中,7项SPECT/CT研究和2项PET/CT研究在两组CT图像(休息或应激)中至少有一组显示肾脏肿块;如果不可见,最常见的是肿瘤要么在视野之外,要么已经被切除了。其中6例SPECT/CT和2例PET/CT显示为恶性肿瘤。心脏SPECT/CT和PET/CT图像显示偶发的肾脏肿块频率不可忽略,CT图像应仔细检查。
