He also gave a history of episodes of loss of consciousness for the past 5\u2005years with a frequency of one per 3\u2005months. On examination, there were melanocytic naevi\u2014one large lesion in the nape of the neck and multiple satellite lesions. On investigation, the cervical cord MRI was normal. The brain MRI and angiography showed a moyamoya pattern. Thus, this patient had congenital melanocytic naevi with Hirayama disease and moyamoya pattern. He was treated with extracranial\u2013intracranial bypass for moyamoya disease. During 6-month follow-up, he has been stable. Although moyamoya syndrome has been associated with several systemic diseases and conditions, the coexistence of a moyamoya pattern with Hirayama disease and melanocytic naevi has not been described so far.<\/jats:p>","DOI":"10.1136\/bcr-2015-212894","type":"journal-article","created":{"date-parts":[[2016,1,8]],"date-time":"2016-01-08T10:07:20Z","timestamp":1452247640000},"page":"bcr2015212894","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Is congenital melanocytic naevus a link between Hirayama disease and moyamoya pattern: a new syndrome or a co-incidence?"],"prefix":"10.1136","volume":"2016","author":[{"given":"Inder","family":"Puri","sequence":"first","affiliation":[{"name":"Department of Neurology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deepti","family":"Vibha","sequence":"additional","affiliation":[{"name":"Department of Neurology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kameshwar","family":"Prasad","sequence":"additional","affiliation":[{"name":"Department of Neurology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rohit","family":"Bhatia","sequence":"additional","affiliation":[{"name":"Department of Neurology, All India Institute of Medical Sciences, New Delhi, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,1,8]]},"reference":[{"key":"2025082803351132000_2016.jan08_2.bcr2015212894.1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.13.5.373"},{"key":"2025082803351132000_2016.jan08_2.bcr2015212894.2","doi-asserted-by":"publisher","DOI":"10.1016\/j.nic.2011.07.009"},{"key":"2025082803351132000_2016.jan08_2.bcr2015212894.3","doi-asserted-by":"publisher","DOI":"10.1016\/j.nic.2011.07.007"},{"key":"2025082803351132000_2016.jan08_2.bcr2015212894.4","doi-asserted-by":"publisher","DOI":"10.1001\/archneur.62.1.120"},{"key":"2025082803351132000_2016.jan08_2.bcr2015212894.5","doi-asserted-by":"publisher","DOI":"10.3340\/jkns.2015.57.6.408"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2015-212894","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,28]],"date-time":"2025-08-28T10:35:18Z","timestamp":1756377318000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2015-212894"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,1,8]]},"references-count":5,"alternative-id":["10.1136\/bcr-2015-212894"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2015-212894","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2016,1,8]]}}}
