“…Based on the location of the air within the spinal cord, pneumorachis can be classified as intradural or extradural. 90 Extradural pneumorachis is more common and is usually benign. Intradural pneumorachis, on the other hand, is indicative of major trauma.…”

Pneumorachis is characterized by the presence of free air in the spinal canal. It is referred by different names in literature such as epidural emphysema, intraspinal air, intraspinal pneumoc(o)ele, spinal epidural and subarachnoid pneumatosis, spinal and epidural emphysema, aerorachia, pneumosaccus, air myelogram, etc. Pneumorachis can be broadly classified as traumatic, iatrogenic, or spontaneous. In this case-based review, we present a case of spontaneous pneumorachis secondary to asthma exacerbation. This is followed by a systematic review of all cases of spontaneous pneumorachis identified in PubMed. The aim of this review is to understand the pathophysiology, common causes and the management of spontaneous pneumorachis.

“…The findings are clinically significant because most previous reports involved young adults. We reviewed the relevant literature regarding cases involving children aged <15 years and retrieved 25 articles reporting 32 cases [3], [4], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29]. In total, 22 boys and 10 girls aged between 1 and 15 years (mean age: 9 years) were identified.…”

Pneumorrhachis refers to the clinical presentation of air within the spinal canal, and it is rarely associated with pneumomediastinum, particularly in young children. Pneumorrhachis associated with pneumomediastinum is generally asymptomatic. Here we report 2 unusual cases involving very young children with pneumorrhachis secondary to pneumomediastinum and present a review of the relevant literature. Case 1 involved a 4-year-old girl who presented with wheezing, violent coughing, and dyspnea associated with bronchiolitis. Case 2 involved a 3-year-old boy who presented with wheezing, violent coughing, and dyspnea associated with interstitial pneumonia possibly caused by graft-versus-host disease with human herpesvirus 6 infection after allogeneic hematopoietic stem cell transplantation. In both cases, pneumorrhachis improved with oxygen inhalation therapy and treatment of the underlying disease. Pneumorrhachis is rarely associated with neurological problems; however, decompressive laminectomy may be indicated to relieve the air block. Because pneumorrhachis is rare in children and neurological sequelae may be difficult to identify, close clinical, and radiographic observations are necessary. Plain radiography is not sufficient, and computed tomography should be performed to rule out intraspinal air.

“…Spontaneous pneumomediastinum and PR can occur when intra-alveolar pressure increases, as occurs with forceful coughing, leads to the rupture of the central pulmonary alveolus. Air can move into the perivascular interstitium and dissect through the fascial planes from the posterior mediastinum or retropharyngeal space through the neural foramina into the epidural space 1 - 3 . Spontaneous pneumomediastinum-associated PR is usually self-limiting, following a generally benign, conservatively managed course.…”
