Melorheostosis is a rare sclerosing bone dysplasia that most commonly affects the lower extremity long bones in a sclerotomal distribution. Melorheostosis of the spine is a particularly rare manifestation of this disease. In the appendicular skeleton, melorheostosis has a pathognomonic imaging appearance of flowing hyperostosis resembling melted candle wax flowing down the margins of a candlestick. In the spine, it can have a variety of imaging manifestations from unilateral focal sclerotic lesions resembling enostoses, to more bulky and deformative hyperostosis that span and fuse multiple adjacent spinal segments. This combination of nonaggressive radiologic features makes melorheostosis a particularly important diagnosis for radiologists to understand so that they may spare their patients unnecessary biopsy. Here we present the clinical features and computed tomography findings in a 33-year-old male with spinal melorheostosis involving the first and second cervical vertebrae.
致密性骨炎是一种罕见的硬化性骨发育异常，最常累及下肢长骨，呈节段性分布。脊柱致密性骨炎是该疾病一种特别罕见的表现形式。在四肢骨骼中，致密性骨炎具有特征性的影像学表现，即呈流注状骨肥厚，类似融化的蜡烛蜡沿烛台边缘流下。在脊柱中，它可有多种影像学表现，从类似骨岛的单侧局灶性硬化性病变，到跨越并融合多个相邻脊柱节段的更广泛且变形的骨肥厚。这种不具侵袭性的放射学特征组合使得致密性骨炎成为放射科医生需要特别了解的一种重要诊断，以便他们避免让患者接受不必要的活检。在此，我们呈现一名33岁男性脊柱致密性骨炎累及第一和第二颈椎的临床特征及计算机断层扫描结果。
