Imaging of a colloid cyst during rupture has been described in only one other instance. The authors report a highly unusual case of a 53-year-old man who presented with acute onset headaches and imaging findings of hydrocephalus caused by a colloid cyst originating from the septum pellucidum and superior surface of the roof of the third ventricle. Interestingly, the colloid cyst revealed imaging signs of intraventricular rupture characterized by a tail-like drainage of cystic contents into the occipital horn of the lateral ventricle. The patient was surgically treated with a craniotomy and transcallosal approach to the colloid cyst, where it was noted that the cyst wall was spontaneously open. This rare case highlights unique imaging findings of a rare event in an infrequent pathology confirmed with intraoperative microscopy. The authors further document the process of cyst rupture and speculate on its pathomechanisms.<\/jats:p>","DOI":"10.3171\/2016.5.jns153015","type":"journal-article","created":{"date-parts":[[2016,7,8]],"date-time":"2016-07-08T14:00:06Z","timestamp":1467986406000},"page":"1779-1782","source":"Crossref","is-referenced-by-count":5,"title":["Imaging of spontaneous intraventricular rupture of a septum pellucidum colloid cyst: case report"],"prefix":"10.3171","volume":"126","author":[{"given":"Harrison J.","family":"Westwick","sequence":"first","affiliation":[{"name":"Division of Neurosurgery, Centre Hospitalier de l'Universit\u00e9 de Montr\u00e9al, H\u00f4pital Notre-Dame, Montreal, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sami","family":"Obaid","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Centre Hospitalier de l'Universit\u00e9 de Montr\u00e9al, H\u00f4pital Notre-Dame, Montreal, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florence","family":"Morin-Roy","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Centre Hospitalier de l'Universit\u00e9 de Montr\u00e9al, H\u00f4pital Notre-Dame, Montreal, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre-Olivier","family":"Champagne","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Centre Hospitalier de l'Universit\u00e9 de Montr\u00e9al, H\u00f4pital Notre-Dame, Montreal, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alain","family":"Bouthillier","sequence":"additional","affiliation":[{"name":"Division of Neurosurgery, Centre Hospitalier de l'Universit\u00e9 de Montr\u00e9al, H\u00f4pital Notre-Dame, Montreal, Quebec, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1-jns153015","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"450","DOI":"10.1227\/00006123-198011000-00004","article-title":"Colloid cysts of the third ventricle","volume":"7","author":"Antunes JL,","year":"1980","unstructured":"Antunes JL, Louis KM, Ganti SR: Colloid cysts of the third ventricle.
