Unlike meningoceles, pseudomeningoceles are CSF full-filled cysts confined by the paraspinous soft tissue, along the normal nerve course, in communication with the spinal subarachnoid spaces. Normally no more than a radiological finding at MRI, in rare instances they might be symptomatic due to their size or might constitute an obstacle during a reconstructive surgery. Methods: A review of the literature was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines in a time span ranging from November 1972 to May 2024. A total of five articles were found meeting the inclusion criteria. A case report at our institution was added to the case history. Results: A 30-year-old man with complete right brachial plexus nerve roots avulsion and a voluminous pseudomeningocele at the C6-C7 level after a motorcycle incident in January 2023. The pseudomeningocele covered the entirety of the injured brachial plexus. Pre-operative external lumbar drainage was utilized to prevent relapse or worsening of the already existing cerebral spinal fluid collection, with good results at 6 months. The full case report is reported in detail. Conclusions: To date, no clear guidelines about the management of post-traumatic pseudomeningoceles are reported in the literature. The lack of symptoms or signs related to them does not usually require any surgical intervention. If not, a possible management strategy with the use of an external lumbar drainage is proposed, a solution already in use in other surgical contexts with successful results in preventing CSF fistula or its relapse.<\/jats:p>","DOI":"10.3390\/neurolint16060126","type":"journal-article","created":{"date-parts":[[2024,12,6]],"date-time":"2024-12-06T09:55:20Z","timestamp":1733478920000},"page":"1742-1749","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Management of Post-Traumatic Pseudomeningocele as Consequence of Root Nerve Avulsion: Case Report and Review of the Literature"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-6479-2766","authenticated-orcid":false,"given":"Leonardo","family":"Bradaschia","sequence":"first","affiliation":[{"name":"Department of Neuroscience \u201cRita Levi Montalcini\u201d, University of Turin, 10126 Turin, Italy"},{"name":"Neurosurgery Unit, Department of Neuroscience \u201cRita Levi Montalcini\u201d, A.O.U.
