The headache was worse in the morning and on bending forwards. This was associated with 1 week history of vomiting and 1 day history of difficulty in walking. Medical history was unremarkable apart from treated hypothyroidism. There was no history of trauma. Observations and physical examination were entirely normal. Routine blood tests including the ESR and clotting profile were normal. Given the history had red flags for headache, a CT scan was ordered and this showed bilateral subdural haematomas. The patient was referred to the regional neurosurgical centre where the haematomas were evacuated with good recovery. A follow-up MRI brain and spine did not show any source of bleeding.<\/jats:p>","DOI":"10.1136\/bcr.09.2011.4771","type":"journal-article","created":{"date-parts":[[2011,11,16]],"date-time":"2011-11-16T07:54:32Z","timestamp":1321430072000},"page":"bcr0920114771","source":"Crossref","is-referenced-by-count":1,"title":["\u2018Idiopathic\u2019 chronic bilateral subdural haematoma \u2013 a separate entity or a missed cause?"],"prefix":"10.1136","volume":"2011","author":[{"given":"Syed Viqar","family":"Ahmed","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Bonny","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sumit","family":"Chandra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2011,11,15]]},"reference":[{"key":"2025082706551079000_2011.nov11_1.bcr0920114771.1","doi-asserted-by":"publisher","DOI":"10.1097\/TA.0b013e3181a5f31c"},{"key":"2025082706551079000_2011.nov11_1.bcr0920114771.2","doi-asserted-by":"publisher","DOI":"10.1016\/S0303-8467(76)80052-2"},{"key":"2025082706551079000_2011.nov11_1.bcr0920114771.3","first-page":"384","article-title":"Spontaneous bilateral subacute subdural hematoma revealing intracranial hypotension.","volume":"14","author":"Souirti","year":"2009","journal-title":"Neurosciences (Riyadh)"},{"key":"2025082706551079000_2011.nov11_1.bcr0920114771.4","first-page":"1538","article-title":"Bilateral subdural hematomas and hearing disturbances caused by spontaneous intracranial hypotension.","volume":"92","author":"Srimanee","year":"2009","journal-title":"J Med Assoc Thai"},{"key":"2025082706551079000_2011.nov11_1.bcr0920114771.5","unstructured":"Scottish Intercollegiate Guidelines Network.
