However, it may mimic genuine neoplasms of the cauda equina. The authors describe a 29-year-old woman with a history of back pain, right leg pain, and urinary incontinence in whom imaging demonstrated an enhancing mass located in the cauda equina at the L1\u20132 interspace. The patient subsequently underwent biopsy and was found to have a focus of ectopic ganglionic tissue that was 1.3 cm in greatest dimension.<\/jats:p>\n<jats:p>To the authors' knowledge, ectopic or heterotopic ganglionic tissue within the cauda equina in a patient without evidence of spinal dysraphism has never been reported. This patient presented with imaging and clinical findings suggestive of a neoplasm, and an open biopsy proved the lesion to be ectopic ganglionic tissue. The authors suggest that ectopic ganglionic tissue be added to the list of differential diagnoses of a space-occupying lesion arising from the cauda equina.<\/jats:p>","DOI":"10.3171\/2015.11.spine141304","type":"journal-article","created":{"date-parts":[[2016,2,12]],"date-time":"2016-02-12T15:13:05Z","timestamp":1455289985000},"page":"937-940","source":"Crossref","is-referenced-by-count":2,"title":["Ectopic ganglion in cauda equina: case report"],"prefix":"10.3171","volume":"24","author":[{"given":"Andrew K.","family":"Conner","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kar-Ming","family":"Fung","sequence":"additional","affiliation":[{"name":"Pathology, University of Oklahoma Health Sciences Center, Oklahoma City, Oklahoma"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo Elle G.","family":"Peterson","sequence":"additional","affiliation":[{"name":"Pathology, University of Oklahoma Health Sciences Center, Oklahoma City, Oklahoma"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chad A.","family":"Glenn","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael D.","family":"Martin","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery and"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1-spine141304","series-title":"Tumors of the Central Nervous System.
