This results in a characteristic midline sagittal cleft, giving the vertebra a "butterfly" appearance on imaging. ✅ Plain Radiograph Widened vertebral body with a central cleft. Adjacent vertebrae show concave endplates due to altered intervertebral disc morphology. Possible bony bridging across the cleft, especially in the thoracic and lumbar spine. Typically, the posterior elements remain intact, distinguishing it from other vertebral defects. ✅CT Scan Clearly delineates the sagittal split and asymmetry in vertebral body development. Identifies osseous bridging or fusion defects. ✅MRI Best modality for assessing associated soft tissue abnormalities and spinal cord involvement. Demonstrates normal or altered intervertebral disc signal at the level of the anomaly. Helps differentiate from fracture, metastases, or infection. ✅Clinical and Biomechanical Implications Often asymptomatic and found incidentally. May alter spinal biomechanics, potentially leading to: Kyphosis or scoliosis Disc herniation Segmental instability Associated anomalies include spinal dysraphism, congenital scoliosis, and syndromic disorders such as Jarcho-Levin syndrome and Alagille syndrome. ✅ Common Differential Diagnoses Compression fracture (check for acute changes and disc height preservation) Hemivertebra (typically unilateral rather than midline) Lytic metastasis (evaluate for adjacent soft tissue involvement) Vertebral osteomyelitis (look for endplate destruction and soft tissue abscesses) #ButterflyVertebra, #CongenitalSpinalAnomaly, #MSKRadiology, #SpineImaging, #Neuroradiology, #SpinalDysraphism, #Scoliosis, #Kyphosis, #CTScan, #MRI "Visualizing MSK Radiology: A Practical Guide to Radiology Mastery" © 2022 MSK MRI Jee Eun Lee All Rights Reserved.
