To calculate the frequencies of incidental extraspinal findings and incidentally detected congenital anomalies or anatomical differences in the lumbar spine on magnetic resonance imaging (MRI) scans of intervertebral discs.
A total of 379 lumbar spine MRI cases were prospectively investigated in the period spanning from August 2016 to January 2018. Both 1.5 and 0.35 Tesla MRI units (Toshiba and Siemens Medical Systems) were used to examine patients with clinically suspected intervertebral disc abnormalities at three MRI diagnostic centers in Khartoum State, Sudan.
Of the 379(100%) patients, 90(23.7%) patients were presented with incidental findings. Among the incidental findings, 39(10.3%) were renal cysts, 10(2.6%) were retroverted uteri, 5(1.3%) were Nabothian cysts, 4(1.1%) were ovarian cysts, 10(2.6%) were uterine fibroids, 3(0.8%) were endometrial thickening, 11(2.9%) were indicative of hydronephrosis, 4(1.1%) were uncovered prostatic enlargement, 2(0.5%) were atrophic kidney, and 1(0.3%) each was of an ectopic kidney and bladder wall thickening, respectively.
A high percentage of extraspinal pathological findings were detected during MRI lumbar spine scans of intervertebral discs. Thus, it is important to be aware of the high percentage of patients who undergo further evaluation given the presence of unexpected findings, but for whom clinical confirmation of these abnormalities is not obtained.
计算在椎间盘磁共振成像（MRI）扫描中偶然发现的脊柱外异常以及偶然检测到的腰椎先天性异常或解剖差异的发生率。
2016年8月至2018年1月期间，对379例腰椎MRI病例进行了前瞻性研究。在苏丹喀土穆州的三个MRI诊断中心，使用1.5特斯拉和0.35特斯拉的MRI设备（东芝和西门子医疗系统）对临床怀疑有椎间盘异常的患者进行检查。
379例（100%）患者中，90例（23.7%）有偶然发现。在这些偶然发现中，肾囊肿39例（10.3%），子宫后倾10例（2.6%），宫颈纳氏囊肿5例（1.3%），卵巢囊肿4例（1.1%），子宫肌瘤10例（2.6%），子宫内膜增厚3例（0.8%），肾积水11例（2.9%），前列腺增生4例（1.1%），肾萎缩2例（0.5%），异位肾和膀胱壁增厚各1例（0.3%）。
在腰椎间盘MRI扫描过程中检测到了高比例的脊柱外病理发现。因此，重要的是要意识到，鉴于存在意外发现，有很大比例的患者需要进一步评估，但这些异常情况未得到临床证实。
