She initially presented 2\u2009weeks earlier with a 7\u2009days history of severe headache, for which she had a CT scan, lumbar puncture and treatment for possible viral meningitis. The headache got worse 4\u2009days after the lumbar puncture. Despite analgesics and bed rest, the headache persisted. A subsequent magnetic imaging scan demonstrated bilateral subdural effusions. She was given supportive treatment, which included advice concerning strict bed rest and analgesia. The headache took several months to abate. A third of patients suffer from post lumbar puncture headaches and this should be explained during informed consenting and post procedure. Not all post lumbar puncture headaches are simple headaches. A post lumbar puncture headache continuing for more than 7\u201314\u2009days after the procedure requires further investigation to exclude life-threatening intracranial complications.<\/jats:p>","DOI":"10.1136\/bcr-2020-239559","type":"journal-article","created":{"date-parts":[[2021,2,5]],"date-time":"2021-02-05T16:07:31Z","timestamp":1612541251000},"page":"e239559","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Delayed diagnosis of bilateral subdural effusions complicating intracranial hypotension in a patient presenting with post lumbar puncture headache"],"prefix":"10.1136","volume":"14","author":[{"given":"Saleheen","family":"Huq","sequence":"first","affiliation":[{"name":"General Medicine, North West Anglia NHS Foundation Trust, Peterborough, Cambridgeshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Menaka G","family":"Iyer","sequence":"additional","affiliation":[{"name":"General Medicine, North West Anglia NHS Foundation Trust, Peterborough, Cambridgeshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4104-9674","authenticated-orcid":false,"given":"Samson O","family":"Oyibo","sequence":"additional","affiliation":[{"name":"Diabetes and Endocrinology, North West Anglia NHS Foundation Trust, Peterborough, Cambridgeshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,2,5]]},"reference":[{"key":"2025082800452523000_14.2.e239559.1","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awv016"},{"key":"2025082800452523000_14.2.e239559.2","doi-asserted-by":"publisher","DOI":"10.1177\/0333102417738202"},{"key":"2025082800452523000_14.2.e239559.3","doi-asserted-by":"publisher","DOI":"10.1136\/pgmj.2006.044792"},{"key":"2025082800452523000_14.2.e239559.4","first-page":"595","article-title":"Post spinal puncture headache, an old problem and new concepts: review of articles about predisposing factors","volume":"4","author":"Jabbari","year":"2013","journal-title":"Caspian J Intern Med"},{"key":"2025082800452523000_14.2.e239559.5","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1177\/2514183X18787371","article-title":"Diagnostic challenges and therapeutic possibilities in spontaneous intracranial hypotension","volume":"2","author":"Beck","year":"2018","journal-title":"Clinical and Translational Neuroscience"},{"key":"2025082800452523000_14.2.e239559.6","doi-asserted-by":"publisher","DOI":"10.1016\/S1474-4422(15)00015-0"},{"key":"2025082800452523000_14.2.e239559.7","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.1971.00490020086010"},{"key":"2025082800452523000_14.2.e239559.8","doi-asserted-by":"publisher","DOI":"10.1136\/bcr-2014-205059"},{"key":"2025082800452523000_14.2.e239559.9","doi-asserted-by":"publisher","DOI":"10.3174\/ajnr.A1041"},{"key":"2025082800452523000_14.2.e239559.10","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.56.12.1746"},{"key":"2025082800452523000_14.2.e239559.11","first-page":"483","article-title":"Does postdural puncture headache left untreated lead to subdural hematoma?
