The patient is a 33-year-old woman with progressive symptoms, including right facial droop, left hemianesthesia, diplopia, and nystagmus. The patient underwent a right extended retrosigmoid approach with intraoperative neuronavigation and neuromonitoring. Lower cranial nerve dissection allowed access to the lateral PMJ. A longitudinal corticotomy was performed above the glossopharyngeal. The CM was removed in a piecemeal fashion. Postoperative MRI confirmed gross-total resection and the patient remained neurologically stable.\n                  <\/jats:p>\n                  <jats:p>\n                    The video can be found here:\n                    <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" ext-link-type=\"uri\" xlink:href=\"https:\/\/youtu.be\/K_TtiTo1RsQ\">https:\/\/youtu.be\/K_TtiTo1RsQ<\/jats:ext-link>\n                    .\n                  <\/jats:p>","DOI":"10.3171\/2019.7.focusvid.1978","type":"journal-article","created":{"date-parts":[[2020,1,6]],"date-time":"2020-01-06T15:54:20Z","timestamp":1578326060000},"page":"V24","source":"Crossref","is-referenced-by-count":0,"title":["Microsurgical resection of an enlarging lateral pontomedullary cavernous malformation"],"prefix":"10.3171","volume":"1","author":[{"given":"Salomon","family":"Cohen-Cohen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Lanzino","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonardo","family":"Rangel-Castilla","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"723","DOI":"10.3171\/2014.5.JNS132276","article-title":"Lateral inferior cerebellar peduncle approach to dorsolateral medullary cavernous malformation","volume":"121","author":"Deshmukh VR","year":"2014","unstructured":"Deshmukh VR, Rangel-Castilla L, Spetzler RF: Lateral inferior cerebellar peduncle approach to dorsolateral medullary cavernous malformation.
