A 27-year-old woman presented with dizziness, headache, and nausea. Magnetic resonance (MR) imaging demonstrated dilation of all ventricles, downward displacement of the third ventricular floor, obliteration of the retrocerebellar cerebrospinal fluid (CSF) space, funnellike enlargement of the entrance of the central canal in the fourth ventricle, and syringomyelia involving mainly the cervical spinal cord. Cine-MR imaging indicated patency of the aqueduct and an absent CSF flow signal in the area of the cisterna magna, which indicated obstruction of the outlets of the fourth ventricle. Although results of radioisotope cisternography indicated failure of CSF absorption, neuroendoscopic third ventriculostomy completely resolved all symptoms as well as the ventricular and spinal cord abnormalities evident on MR images. Neuroendoscopic third ventriculostomy is an important option for treating hydrocephalus in patients with fourth ventricle outlet obstruction.<\/jats:p>","DOI":"10.3171\/jns.2000.93.2.0326","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:27:54Z","timestamp":1242235674000},"page":"326-329","source":"Crossref","is-referenced-by-count":45,"title":["Successful neuroendoscopic third ventriculostomy for hydrocephalus and syringomyelia associated with fourth ventricle outlet obstruction"],"prefix":"10.3171","volume":"93","author":[{"given":"Takaichi","family":"Suehiro","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takanori","family":"Inamura","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshihiro","family":"Natori","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masayuki","family":"Sasaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masashi","family":"Fukui","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"672","DOI":"10.3171\/jns.1971.35.6.0672","article-title":"Hydrocephalus due to membranous obstruction of the fourth ventricle.","volume":"35","author":"Amacher","year":"1971"},{"key":"b2","series-title":"Acta Neurochir","doi-asserted-by":"publisher","first-page":"27","DOI":"10.1007\/BF01428498","article-title":"Long-term results of fourth ventriculo-cisternostomy in complex versus simplex atresias of the fourth ventricle outlets.","volume":"134","author":"Chai","year":"1995"},{"key":"b3","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"448","DOI":"10.3171\/jns.1999.90.3.0448","article-title":"Failure of third ventriculostomy in the treatment of aqueductal stenosis in children.","volume":"90","author":"Cinalli","year":"1999"},{"key":"b4","series-title":"Neurosurgery","first-page":"1323","article-title":"The role of endoscopic third ventriculostomy in the management of shunt malfunction.","volume":"43","author":"Cinalli","year":"1998"},{"key":"b5","series-title":"Child Brain","first-page":"81","article-title":"On the pathology of experimental hydrocephalus induced by artificial increase in endoventricular CSF pulse pressure.","volume":"5","author":"Di Rocco","year":"1979"},{"key":"b6","series-title":"Radiology","doi-asserted-by":"publisher","first-page":"467","DOI":"10.1148\/radiology.178.2.1987610","article-title":"Normal flow patterns of intracranial and spinal cerebrospinal fluid defined with phase-contrast cine MR imaging.","volume":"178","author":"Enzmann","year":"1991"},{"key":"b7","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"297","DOI":"10.3171\/jns.1994.81.2.0297","article-title":"Sialorrhea from fourth ventricle hydrocephalus.
