Pneumorrhachis (PR) is a rare radiological condition characterized by the presence of intraspinal air. PR is commonly classified as spontaneous (nontraumatic), traumatic, or iatrogenic, and iatrogenic PR is the most common and often occurs secondary to invasive procedures such as epidural anesthesia, lumbar puncture, or spinal surgery. PR is usually asymptomatic, but it can produce symptoms associated with its underlying pathology. Here, we report a rare case of intramedullary cervical PR following a cervical epidural steroid injection (ESI) and include pertinent discussion.
气脊（PR）是一种罕见的影像学表现，其特征为椎管内存在空气。PR 通常分为自发性（非外伤性）、外伤性和医源性，医源性 PR 最为常见，常继发于硬膜外麻醉、腰椎穿刺或脊柱手术等有创操作。PR 通常无症状，但也可出现与其基础病变相关的症状。本文报告了 1 例颈椎硬膜外类固醇注射（ESI）后发生的罕见颈髓内 PR 病例，并进行了相关讨论。
