To determine the prevalence of incidental findings on magnetic resonance imaging (MRI) scans of the cervical, thoracic and lumbar spine in a paediatric population.
We evaluated 190 spinal MRI examinations of patients aged ≤ 18 years of age. The study included only patients for whom complete medical records were available and who underwent complete MRI examination of the cervical, thoracic or lumbar spine, including whole-spine sagittal T2-weighted sequences. Imaging findings not related to the symptom or indication for MRI were considered incidental findings.
Of the 190 MRI examinations evaluated, 110 were in women and 80 were in men. The mean age of the study population was 12.46 ± 3.68 years. The main clinical indications for MRI in the sample were lumbago, scoliosis, dorsalgia and cervicalgia. Incidental findings were detected in the cervical, thoracic and lumbar spine in 40 (21.05%), 26 (13.83%) and 43 (22.63%) of the patients, respectively. The most common were (in the cervical spine) reversal/correction of the normal curvature; (in the thoracic spine) intravertebral disc herniation (Schmorl's node) and disc dehydration; and (in the lumbar spine) disc protrusion (12 cases), Schmorl's node (5 cases) and spondylolysis (4 cases).
Incidental findings on MRI of the spine are less common in the paediatric population than in the adult population. Nevertheless, careful clinical evaluation of paediatric patients with complaints of axial and radiating pain is necessary in order to determine the correlation between symptoms and imaging findings.
确定儿科人群颈椎、胸椎和腰椎磁共振成像（MRI）扫描中偶然发现的患病率。
我们评估了190例年龄≤18岁患者的脊柱MRI检查。该研究仅纳入了有完整病历且接受了颈椎、胸椎或腰椎完整MRI检查的患者，包括全脊柱矢状面T2加权序列。与MRI症状或指征无关的影像学发现被视为偶然发现。
在评估的190例MRI检查中，女性110例，男性80例。研究人群的平均年龄为12.46±3.68岁。样本中MRI的主要临床指征为腰痛、脊柱侧弯、背痛和颈痛。分别在40例（21.05%）、26例（13.83%）和43例（22.63%）患者的颈椎、胸椎和腰椎中发现了偶然发现。最常见的是（颈椎）正常曲度的反转/矫正；（胸椎）椎间盘内突出（施莫尔氏结节）和椎间盘脱水；以及（腰椎）椎间盘突出（12例）、施莫尔氏结节（5例）和椎弓峡部裂（4例）。
脊柱MRI的偶然发现在儿科人群中比在成人人群中少见。然而，对于有轴向和放射性疼痛主诉的儿科患者，进行仔细的临床评估以确定症状与影像学发现之间的相关性是必要的。
