To the best of our knowledge, there have been only 2 previously reported cases of patients with posterior CPPD lesions in this region that have led to cervical myelopathy. We report the case of a 70-year-old man presenting with neck pain and cervical myelopathy with multilevel stenosis from C1-C6. The stenosis was worst at C1-C2, secondary to compression by a CPPD lesion posterior to the spinal cord. The patient underwent a C2-C6 laminectomy and fusion with resection of the CPPD lesion. In this report, we discuss the patient and present a novel theory to explain the preponderance of CPPD lesions in the CCJ occurring anteriorly and not posteriorly to the spinal cord.<\/jats:p>","DOI":"10.1136\/bcr-2016-214771","type":"journal-article","created":{"date-parts":[[2016,3,14]],"date-time":"2016-03-14T13:57:53Z","timestamp":1457963873000},"page":"bcr2016214771","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Posterior C1-C2 calcium pyrophosphate dihydrate crystal deposition disease"],"prefix":"10.1136","volume":"2016","author":[{"given":"Isaac Bing-Yi","family":"Ng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Knarik","family":"Arkun","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ron I","family":"Riesenburger","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,3,14]]},"reference":[{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.1","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-56-5-711"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.2","doi-asserted-by":"publisher","DOI":"10.1148\/122.1.1"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.3","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.145.4.777"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.4","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1989.71.1.0141"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.5","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.54.7.658"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.6","doi-asserted-by":"publisher","DOI":"10.1227\/00006123-199508000-00023"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.7","doi-asserted-by":"publisher","DOI":"10.3171\/jns.1996.85.5.0803"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.8","doi-asserted-by":"publisher","DOI":"10.1007\/s002560050164"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.9","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-199601150-00017"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.10","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.159.2.189"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.11","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.216.1.r00jl36213"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.12","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-006-0273-3"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.13","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/75.2.187"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.14","doi-asserted-by":"publisher","DOI":"10.1097\/00007632-198807000-00026"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.15","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmr.2015.04.008"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.16","doi-asserted-by":"publisher","DOI":"10.1016\/j.spinee.2014.04.014"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.17","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0103451"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.18","doi-asserted-by":"publisher","DOI":"10.2106\/JBJS.F.01322"},{"key":"2025042702575974000_2016.mar14_1.bcr2016214771.19","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMicm1100764"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2016-214771","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,27]],"date-time":"2025-04-27T09:58:08Z","timestamp":1745747888000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2016-214771"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,3,14]]},"references-count":19,"alternative-id":["10.1136\/bcr-2016-214771"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2016-214771","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,3,14]]}}}
