Congenital absence of a vertebral pedicle in the cervical spine, a rare disorder, was observed in a 41-year-old woman. The disorder may be confused with a "dumbbell" tumor and erosion by a tortuous vertebral artery. The diagnosis is established by characteristic radiologic changes, especially in oblique roentgenograms, myelograms, and CT scans. Nerve root decompression was performed by hemilaminectomy at the level of the fifth cervical vertebra. There was little relief of pain, the chief preoperative complaint. Surgery may not be indicated for patients with congenital absence of a vertebral pedicle.
在一名41岁女性中观察到颈椎先天性椎弓根缺如，这是一种罕见的病症。该病症可能与“哑铃状”肿瘤以及迂曲椎动脉造成的侵蚀相混淆。通过特征性的放射学改变来确立诊断，尤其是在斜位X线片、脊髓造影和CT扫描中。在颈椎第五节水平进行半椎板切除术以实施神经根减压。患者术前的主要诉求是疼痛，但术后疼痛缓解甚微。对于先天性椎弓根缺如的患者，可能不宜进行手术。
