He had a history of skull base trauma and endoscopic repair for cerebrospinal fluid rhinorrhoea 7 years earlier. Imaging revealed a lesion adjacent to a cribriform plate defect, initially suggesting a non-expanding meningocele. However, intraoperatively, the lesion was identified as a spheno-ethmoidal mucocele with orbital extension. Endoscopic drainage and marsupialisation were performed, resulting in immediate resolution of proptosis and marked improvement in visual acuity. Follow-up imaging showed no residual lesion or optic nerve compression. This case illustrates a rare spheno-ethmoidal mucocele presenting as compressive optic neuropathy, emphasising the need for a broad differential diagnosis and multidisciplinary collaboration when evaluating skull base lesions.<\/jats:p>","DOI":"10.1136\/bcr-2025-267011","type":"journal-article","created":{"date-parts":[[2025,12,12]],"date-time":"2025-12-12T10:40:19Z","timestamp":1765536019000},"page":"e267011","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Imposter behind the eye: spheno-ethmoidal mucocele mimicking meningocele with compressive optic neuropathy"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4417-8703","authenticated-orcid":false,"given":"Varun","family":"Jerath","sequence":"first","affiliation":[{"name":"Otorhinolaryngology, Army Hospital Research and Referral, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-4103-0896","authenticated-orcid":false,"given":"Sachu Jacob","family":"James","sequence":"additional","affiliation":[{"name":"Otorhinolaryngology, Army Hospital Research and Referral, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ajit","family":"Singh","sequence":"additional","affiliation":[{"name":"Neurosurgery, Army Hospital Research and Referral, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saurabh","family":"Maheshwari","sequence":"additional","affiliation":[{"name":"Radiology, Army Hospital Research and Referral, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,12,12]]},"reference":[{"key":"2025121202400994000_18.12.e267011.1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1970.32.4.0443"},{"key":"2025121202400994000_18.12.e267011.2","doi-asserted-by":"crossref","unstructured":"Watkinson JC , Clarke RW , eds.
