Pneumorrhachis after an upper respiratory infection: a case report of a rare phenomenon
Llewellyn K, Johnson R, Krueger EM, Seibly JM. Pneumorrhachis After an Upper Respiratory Infection: A Case Report of a Rare Phenomenon. Cureus. 2020 Apr 22;12(4):e7784. doi: 10.7759/cureus.7784.
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.
