Abstract

Melorheostosis, an uncommon mesenchymal dysplasia, rarely affects the axial skeleton. We describe the imaging findings of melorheostosis involving the cervical and upper thoracic spine. Radiographs and CT showed unilateral well-marginated undulating zones of cortical hyperostosis involving multiple vertebrae that were contiguous with a coalescent ossified right paravertebral mass. MR imaging showed zones of signal intensity void on all pulse sequences without contrast enhancement. Conservative management was elected because of lack of interval clinical and imaging changes for 8 years.

摘要

骨纹状肥大症是一种罕见的间质性发育异常,很少累及中轴骨骼。我们描述了累及颈椎和上胸椎的骨纹状肥大症的影像学表现。X线平片和CT显示单侧边界清晰的皮质骨增生呈波浪状,累及多个相邻椎体,并与右侧椎旁融合性骨化肿块相连。磁共振成像显示在所有脉冲序列上均为信号强度缺失区,无强化。由于8年来临床和影像学均无变化,故选择保守治疗。
