The traumatic pneumomyelogram

Abstract

Air within the cervical subarachnoid space secondary to skull trauma (traumatic air myelogram or pneumomyelogram) has not been reported previously. Such a case is presented and the findings are reviewed in the light of existing literature.

Pediatric Traumatic Pneumorrhachis: Case Report

“…PR being secondary to trauma is rare and it may contain isolated head trauma [9], cervical trauma [10], thoracic trauma [11], abdominal trauma [1], and pelvic trauma [12] or spinal trauma in several combinations [13]. Epidural PR may be seen being secondary to traumatic pneumothorax [14].…”

“…Air in the spinal canal was first reported by Gordon and Hardman [1], and the term pneumorrhachis (PR) was first used by Newbold et al [2] exactly 10 years after this. It can be called erorachia [3], intraspinal pneumocele [4], pneumosaccus [5], pneumomyelogram [1], or simply intraspinal air [6].…”

“…It can be called erorachia [3], intraspinal pneumocele [4], pneumosaccus [5], pneumomyelogram [1], or simply intraspinal air [6]. While PR can be classified as extradural or intradural according to its localization, it is classified as nontraumatic, traumatic, and iatrogenic etiologically [7].…”

Epidural Gas Accumulation in Connection with Canine Degenerative Lumbosacral Disease

“…Pneumorrhachis is a rare clinical diagnosis of gas within the spinal canal and was reported for the first time in human medicine in 1977 (1). After a trauma, gas can enter the spinal canal from a pneumothorax/pneumomediastinum or through open skull fractures (1–6).…”

“…After a trauma, gas can enter the spinal canal from a pneumothorax/pneumomediastinum or through open skull fractures (1–6). Epidural injections or surgical interventions in the head or spine can also lead to iatrogenic pneumorrhachis (7–12).…”
