It can be asymptomatic or present with symptoms of myelopathy due to spinal cord or nerve root compression. MRI is the initial imaging modality to diagnose this condition. CT myelography is the imaging modality of choice for detecting the actual site of communication between the subarachnoid space and arachnoid cysts; hence, it plays a pivotal role in surgical planning. We describe the imaging features of a symptomatic large spinal extradural arachnoid cyst and cord changes in a 12-year-old boy, who presented with paraparesis. CT and MR myelography helped in surgical planning by delineating the cyst morphology and the dural defect. It is an uncommon cause of myelopathy and must be accurately identified through imaging.<\/jats:p>","DOI":"10.25259\/nmji_912_2023","type":"journal-article","created":{"date-parts":[[2025,10,1]],"date-time":"2025-10-01T10:27:42Z","timestamp":1759314462000},"page":"281-283","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spinal extradural arachnoid cyst causing paraparesis in a child"],"prefix":"10.25259","volume":"38","author":[{"given":"SHARIQ AHMAD","family":"SHAH","sequence":"first","affiliation":[{"name":"Department of Neuroradiology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BHERU DAN","family":"CHARAN","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"LEVE JOSEPH DEVARAJAN","family":"SEBASTIAN","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"SHWETA","family":"KEDIA","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"AJAY","family":"GARG","sequence":"additional","affiliation":[{"name":"Department of Neuroradiology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2025,10,1]]},"reference":[{"key":"10.25259\/NMJI_912_2023\/ref-1","doi-asserted-by":"publisher","first-page":"355","DOI":"10.3340\/jkns.2013.54.4.355","article-title":"Spinal extradural arachnoid cyst","volume":"54","author":"Choi","year":"2013","journal-title":"J Korean Neurosurg Soc"},{"key":"10.25259\/NMJI_912_2023\/ref-2","doi-asserted-by":"publisher","first-page":"E6","DOI":"10.3171\/foc.2007.22.2.6","article-title":"Spinal extradural arachnoid cysts: Clinical, radiological, and surgical features","volume":"22","author":"Liu","year":"2007","journal-title":"Neurosurg Focus"},{"key":"10.25259\/NMJI_912_2023\/ref-3","doi-asserted-by":"publisher","first-page":"231","DOI":"10.1136\/jnnp.26.3.231","article-title":"The radiological appearances of spinal extradural arachnoid cysts","volume":"26","author":"Dastur","year":"1963","journal-title":"J Neurol Neurosurg Psychiatry"},{"key":"10.25259\/NMJI_912_2023\/ref-4","doi-asserted-by":"publisher","first-page":"116","DOI":"10.3171\/spi.1999.91.1.0116","article-title":"Multiple extradural arachnoid cysts as a cause of spinal cord compression in a child.
