The authors report the case of a 3-year-old boy in whom a benign ventricular cyst developed in the aqueduct. The patient became drowsy after having complained of headache and vomiting; MR imaging revealed mild triventricular dilation and a normal-sized fourth ventricle. Repeated MR imaging performed 1 week later revealed an aqueductal cyst that had markedly enlarged during the intervening period. An external ventricular drainage system was installed, but recovery of consciousness in the child was unsatisfactory and a new bilateral internuclear ophthalmoplegia developed. Fenestration of the cyst wall and placement of a ventriculocisternostomy in the third ventricle were performed simultaneously by using a flexible neuroendoscope. By 2 weeks postsurgery, the patient's neurological symptoms had completely resolved. This case illustrates that simple rerouting of ventricular cerebrospinal fluid (CSF) can aggravate the symptoms of this rare lesion by causing severe compression of periaqueductal structures by a cyst that maintains a high intracystic pressure. Endoscopic surgery was an excellent choice of treatment to achieve both cyst fenestration and normalization of intracranial CSF pressure by creating a ventriculocisternostomy.<\/jats:p>","DOI":"10.3171\/jns.2000.92.3.0490","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T17:32:51Z","timestamp":1242235971000},"page":"490-492","source":"Crossref","is-referenced-by-count":7,"title":["Benign aqueductal cyst causing bilateral internuclear ophthalmoplegia after external ventricular drainage"],"prefix":"10.3171","volume":"92","author":[{"given":"Masahiro","family":"Shin","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsuhiro","family":"Nishihara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shigeo","family":"Iai","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsuneyoshi","family":"Eguchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"J Clin Neuroophthalmol","first-page":"278","article-title":"Internuclear ophthalmoplegia from intracranial tumor.","volume":"10","author":"Arnold","year":"1990"},{"key":"b2","series-title":"Neurology","doi-asserted-by":"publisher","first-page":"1850","DOI":"10.1212\/WNL.40.12.1850","article-title":"Internuclear ophthalmoplegia in the Chiari type II malformation.","volume":"40","author":"Arnold","year":"1990"},{"key":"b3","series-title":"AJNR","first-page":"471","article-title":"MR of aqueductal stenosis: evidence of a broad spectrum of tectal distortion.","volume":"10","author":"Barkovich","year":"1989"},{"key":"b4","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"1066","DOI":"10.1136\/jnnp.47.10.1066","article-title":"A suprasellar subarachnoid pouch; aetiological considerations.","volume":"47","author":"Binitie","year":"1984"},{"key":"b5","series-title":"AJNR","first-page":"458","article-title":"Aqueduct compression from venous angioma: MR findings.","volume":"17","author":"Blackmore","year":"1996"},{"key":"b6","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"227","DOI":"10.3171\/jns.1999.90.2.0227","article-title":"Sylvian aqueduct syndrome and global rostral midbrain dysfunction associated with shunt malfunction.","volume":"90","author":"Cinalli","year":"1999"},{"key":"b7","series-title":"Neurology","doi-asserted-by":"publisher","first-page":"629","DOI":"10.1212\/WNL.20.7.629","article-title":"Internuclear ophthalmoplegia as an early sign of brainstem tumors.","volume":"20","author":"Cogan","year":"1970"},{"key":"b8","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"383","DOI":"10.1136\/jnnp.30.5.383","article-title":"Some neuro-ophthalmological observations.","volume":"30","author":"Fisher","year":"1967"},{"key":"b9","series-title":"J Neurol Sci","doi-asserted-by":"publisher","first-page":"53","DOI":"10.1016\/S0022-510X(96)05330-0","article-title":"Binocular saccadic eye movements in multiple sclerosis.","volume":"148","author":"Flipse","year":"1997"},{"key":"b10","series-title":"J Neurol Neurosurg Psychiatry","first-page":"564","article-title":"Bilateral internuclear ophthalmoplegia in multiple sclerosis.","volume":"6","author":"Gass","year":"1997"},{"key":"b11","series-title":"Ophthalmology","doi-asserted-by":"publisher","first-page":"1162","DOI":"10.1016\/S0161-6420(90)32441-7","article-title":"Early magnetic resonance imaging in acute traumatic internuclear ophthalmoplegia.","volume":"97","author":"Haller","year":"1990"},{"key":"b12","series-title":"Clin Radiol","doi-asserted-by":"publisher","first-page":"527","DOI":"10.1016\/S0009-9260(87)80145-9","article-title":"Magnetic resonance imaging of peri-aqueductal lesions.","volume":"38","author":"Lee","year":"1987"},{"key":"b13","series-title":"Neurosurgery","doi-asserted-by":"publisher","first-page":"822","DOI":"10.1227\/00006123-198511000-00018","article-title":"Bilateral internuclear ophthalmoplegia due to hydrocephalus: a case report.","volume":"17","author":"Nishizaki","year":"1985"},{"key":"b14","series-title":"Surg Neurol","doi-asserted-by":"publisher","first-page":"230","DOI":"10.1016\/0090-3019(93)90072-9","article-title":"Aqueductal stenosis due to mesencephalic venous malformation: case report.","volume":"40","author":"Oka","year":"1993"},{"key":"b15","series-title":"Childs Nerv Syst","doi-asserted-by":"publisher","first-page":"257","DOI":"10.1007\/BF00299008","article-title":"Primary intracranial arachnoidal cysts.
