Introduction: Congenital vertebral segmentation anomalies are a heterogeneous group of developmental malformations that may lead to progressive spinal deformity during growth. They are frequently associated with extra-spinal abnormalities, particularly involving the genitourinary system; therefore, systematic screening for associated visceral, especially renal, anomalies is warranted. Case presentation: We report the case of a 7-year-old girl referred for evaluation of a progressive lumbar spinal deformity. Clinical examination revealed trunk asymmetry, pelvic obliquity, and a moderate lumbar paravertebral prominence. Standing full-spine radiographs demonstrated multilevel vertebral segmentation anomalies with vertebral blocks extending from L1 to L5, associated with mild congenital lumbar scoliosis. Spinal magnetic resonance imaging confirmed the vertebral abnormalities and excluded spinal cord and conus medullaris involvement. It also showed an empty left renal fossa, suggesting an associated renal developmental anomaly compatible with a suspected renal fusion anomaly. Abdominal ultrasonography confirmed the absence of a kidney within the left renal fossa. During two years of follow-up, moderate progression of the spinal deformity was observed without neurological impairment. Conclusion: This case highlights the importance of systematic screening for associated visceral anomalies in children with congenital vertebral malformations. It also emphasizes the need for multidisciplinary management and long-term clinical, functional, and radiological follow-up to monitor deformity progression throughout growth.
