Although unusual, malignant transformation with leptomeningeal seeding into the brain or spinal cord may occur years after the initial diagnosis. The authors report a unique case of multifocal benign meningeal melanocytoma involving both cerebellopontine angles and the thoracic spinal cord, with associated diffuse leptomeningeal hyperpigmentation. They review the literature relevant to this topic and discuss the radiological and pathological features of this disease as well as its treatment options.<\/jats:p>","DOI":"10.3171\/2009.3.jns081096","type":"journal-article","created":{"date-parts":[[2009,4,10]],"date-time":"2009-04-10T13:53:15Z","timestamp":1239371595000},"page":"488-491","source":"Crossref","is-referenced-by-count":34,"title":["Multifocal meningeal melanocytoma: a new pathological entity or the result of leptomeningeal seeding?"],"prefix":"10.3171","volume":"111","author":[{"given":"Youssef","family":"Ali","sequence":"first","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ralph","family":"Rahme","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ronald","family":"Moussa","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gerard","family":"Abadjian","sequence":"additional","affiliation":[{"name":"Pathology, and"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lina","family":"Menassa-Moussa","sequence":"additional","affiliation":[{"name":"Radiology, Saint-Joseph University Faculty of Medicine and H\u00f4tel-Dieu de France, Beirut, Lebanon"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elie","family":"Samaha","sequence":"additional","affiliation":[{"name":"Departments of Neurosurgery,"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"issue":"1 Suppl","key":"b1-1110488","series-title":"J Neurosurg","first-page":"96","article-title":"Neurocutaneous melanosis presenting with hydrocephalus.
