Neurological examination localised a lesion to the T3\u2013L3 spinal cord segments. Magnetic resonance imaging of the thoracolumbar spine showed a well\u2010defined extradural T1\u2010weighted hyperintense non\u2010contrast\u2010enhancing mass, initially suggesting a potential haemorrhagic component. Exploratory surgery revealed a brownish extradural lumbar mass. Histologic examination concluded to a melanoma, most probably metastatic given the animal's previous medical history. This report highlights the importance of collecting a complete medical history, which can help in obtaining a preliminary differential diagnosis in cats with clinical signs of myelopathy. Although the location of this metastasis is particularly unusual both in human and veterinary medicine, making optimal treatment challenging for neurosurgeon, our increased understanding of immune and tumour cell biology during the past decade is likely to improve the future treatments of feline melanoma and its metastases.<\/jats:p>","DOI":"10.1002\/vms3.1248","type":"journal-article","created":{"date-parts":[[2023,9,1]],"date-time":"2023-09-01T15:26:35Z","timestamp":1693581995000},"page":"2393-2398","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Metastatic extradural melanoma of the lumbar spine in a cat"],"prefix":"10.1002","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2396-1301","authenticated-orcid":false,"given":"Sabrina","family":"Fert","sequence":"first","affiliation":[{"name":"Department of Neurology Veterinary Hospital Center Fr\u00e9gis Gentilly France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pablo","family":"River","sequence":"additional","affiliation":[{"name":"Department of Surgery Veterinary Hospital Center Onlyvet Saint Priest France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laura","family":"Bondonny","sequence":"additional","affiliation":[{"name":"Department of Surgery Veterinary Hospital Center Onlyvet Saint Priest France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurent","family":"Cauzinille","sequence":"additional","affiliation":[{"name":"Department of Neurology Veterinary Hospital Center Fr\u00e9gis Gentilly France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,9]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/ICB.0000000000000163"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198707000-00003"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.4142\/jvs.2016.17.2.225"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrd3847"},{"key":"e_1_2_11_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tvjl.2014.12.015"},{"key":"e_1_2_11_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcpa.2013.11.157"},{"key":"e_1_2_11_8_1","doi-asserted-by":"publisher","DOI":"10.3171\/2014.11.FOCUS14716"},{"key":"e_1_2_11_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(17)30429-1"},{"key":"e_1_2_11_10_1","volume-title":"Tumors in domestic animals","author":"Dubielzig R.
