AbstractPaediatric spinal pathologies are commonly encountered in clinical practice. This article summarises the normal appearance of lumbar ultrasonography (LUS) and the imaging techniques used to examine the spine in neonates. The last section of this article is a pictorial illustration of ultrasonography and magnetic resonance imaging (MRI) features of common paediatric spinal pathologies. These include filar cyst, arachnoid cyst, filarfibrolipoma, low-lying cord, syringomyelia, myelomeningocele, Chiari malformations and sacrococcygeal teratoma. Current literature and guidelines on the indications for imaging and available modalities for investigation of occult spinal dysraphism are also reviewed. Isolated simple sacral dimple is no longer an indication for neonatal LUS. Indications for LUS include other cutaneous stigmata, abnormal antenatal ultrasound, and low-risk congenital anomalies. For neonates presenting with neurological deficit, discharging lesion or high-risk congenital anomalies, MRI is indicated. This review also proposes a diagnostic flowchart for better triage of patients to the appropriate modality of imaging in order to achieve satisfactory diagnostic accuracy and enhance cost-effectiveness. © 2013 Hong Kong College of Radiologists.
