The "Scalpel sign" is a radiological sign which can be identified on magnetic resonance imaging and indicates dorsal compression of the spinal cord [1]. Prior descriptions of a "Scalpel sign" have been reported in the literature and the awareness and identification of this pathognomonic sign may aid in the rapid diagnosis and treatment of patients with dorsal arachnoid web, dorsal arachnoid cyst or ventral cord herniation. We describe 3 cases which highlight these rare conditions for which this sign is pathognomonic and summarize the pertinent literature related to these disorders [1,2].
“手术刀征”是一种可在磁共振成像上识别的放射学征象，提示脊髓背侧受压[1]。文献中已有关于“手术刀征”的先前描述，认识和识别这一具有诊断意义的征象可能有助于对患有背侧蛛网膜网、背侧蛛网膜囊肿或腹侧脊髓疝的患者进行快速诊断和治疗。我们描述了3例突出显示该征象具有诊断意义的罕见病例，并总结了与这些疾病相关的相关文献[1,2]。
