To assess extraspinal findings (ESFs) prevalence in lumbar spine MRI, including clinically significant findings using a systematic approach, and to determine their reporting rate. Lumbar spine MRI scans were retrospectively reviewed over 18 months by two radiologists. Reading discrepancies were resolved by consensus. ESFs were classified according to the involved system, clinical diagnosis, and clinical significance. The reporting rate was estimated by referring to the original report. There were 1509 ESFs in 1322/4250 patients with a substantial agreement between the two radiologists (kappa = 0.8). Almost half (621/1322) were in the 45-60 age group. Females represented 56.6% (748/1322). 74.2% (1120/1509) of the ESFs involved the urinary system among which 79.6% (892/1120) were renal cysts. Clinically significant findings represented 8.7% (131/1509) among which hydronephrosis represented 23% (30/131). First time detected malignant lesions represented 4.6% (6/131). ESFs reporting rate was 47.3%. 58.8% of the clinically significant ESFs were not reported. ESFs prevalence was 31.1%. The Urinary system was the most commonly involved. Most ESFs were benign warranting no further workup. However, clinically significant ESF were not infrequently detected. More than half of the clinically significant findings were not reported. A systematic review of MRI images is highly recommended to improve patient's outcome.
评估腰椎磁共振成像中的脊柱外发现（ESFs）的患病率，包括使用系统方法评估临床显著发现，并确定其报告率。18 个月期间，两位放射科医生对腰椎磁共振成像扫描进行了回顾性审查。通过共识解决了阅读差异。根据所涉及的系统、临床诊断和临床意义对 ESFs 进行分类。通过参考原始报告估计报告率。在 4250 名患者中的 1322 名患者中发现了 1509 个 ESFs，两位放射科医生之间存在实质性一致性（kappa = 0.8）。将近一半（621/1322）的患者年龄在 45-60 岁之间。女性占 56.6%（748/1322）。在 1509 个 ESFs 中，有 74.2%（1120/1509）涉及泌尿系统，其中 79.6%（892/1120）为肾囊肿。有临床意义的发现占 8.7%（131/1509），其中肾积水占 23%（30/131）。首次发现的恶性病变占 4.6%（6/131）。ESFs 的报告率为 47.3%。58.8%的有临床意义的 ESFs 未报告。ESFs 的患病率为 31.1%。泌尿系统最常受累。大多数 ESFs 为良性，无需进一步检查。然而，有临床意义的 ESF 并不少见。超过一半的有临床意义的发现未被报告。强烈建议对 MRI 图像进行系统审查，以改善患者的预后。
