Pneumorrhachis After an Upper Respiratory Infection: A Case Report of a Rare Phenomenon

Abstract

Pneumorrhachis (PR) is the presence of free air within the spinal canal. It is generally benign and improves with conservative management. Case reports and a literature review exist documenting the existence and potential pathogenesis of this phenomenon, but no evidence-based guidelines exist documenting what treatment, if any, is indicated for this condition. We present a case of a 21-year-old male who developed PR after a preceding upper respiratory tract infection. His symptoms improved with expectant management and administration of high-flow oxygen. The purpose of this case report is to add to the scarce existing literature reporting this condition and to provide a short review of literature detailing the pathogenesis of PR.
