The lining of the cyst consisted of a single layer of pegshaped epithelial cells rich in organelles and glycogen. Their free border had numerous microvilli but no cilia, and their basal portions rested on a basement membrane. Tight junctions and interdigitations were frequent between contiguous cells. The blood vessels were fenestrated. Since these features characterize developing choroidal epithelial cells, we felt the diagnosis of choroidal epithelial cyst was justified. Cysts lined by choroidal epithelium may continue to secrete cerebrospinal fluid after surgical extirpation when this is incomplete. Accumulation of the fluid in the partially excised cyst bed may therefore account for recurrence of symptoms.<\/jats:p>","DOI":"10.3171\/jns.1977.47.6.0955","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:17:16Z","timestamp":1241709436000},"page":"955-960","source":"Crossref","is-referenced-by-count":32,"title":["Choroidal epithelial cyst"],"prefix":"10.3171","volume":"47","author":[{"given":"Atsuo","family":"Koto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dikran S.","family":"Horoupian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenneth","family":"Shulman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Zentralbl Neurochir","first-page":"39","article-title":"Angeborene Ependymzysten.","volume":"31","author":"Argyopoulos","year":"1970"},{"key":"b2","series-title":"J Neuropathol Exp Neurol","doi-asserted-by":"publisher","first-page":"50","DOI":"10.1097\/00005072-196201000-00004","article-title":"Intracranial cerebellar meningo-encephalocele (posterior fossa cyst) causing hydrocephalus by compression at the incisura tentorii.","volume":"21","author":"Alvord","year":"1962"},{"key":"b3","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"763","DOI":"10.1136\/jnnp.35.6.763","article-title":"Non-communicating supratentorial subarachnoid cysts.","volume":"35","author":"Bhandari","year":"1972"},{"key":"b4","series-title":"J Neurol Neurosurg Psychiatry","doi-asserted-by":"publisher","first-page":"611","DOI":"10.1136\/jnnp.36.4.611","article-title":"Ependymal lined paraventricular cerebral cysts; a report of three cases.","volume":"36","author":"Bouch","year":"1973"},{"key":"b5","series-title":"J Neuropathol Exp Neurol","doi-asserted-by":"publisher","first-page":"16","DOI":"10.1097\/00005072-195110010-00002","article-title":"Heterotopic glial nests in the subarachnoid space: histopathologic characteristics, mode of origin and relation to meningeal gliomas.","volume":"10","author":"Cooper","year":"1951"},{"key":"b6","series-title":"Brain Res","doi-asserted-by":"publisher","first-page":"197","DOI":"10.1016\/0006-8993(70)90324-0","article-title":"The choroid plexus: a historical review.","volume":"18","author":"Dohrmann","year":"1970"},{"key":"b7","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"506","DOI":"10.3171\/jns.1970.33.5.0506","article-title":"Human choroid plexus: a light and electron microscopic study.","volume":"33","author":"Dohrmann","year":"1970"},{"key":"b8","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"75","DOI":"10.3171\/jns.1974.41.1.0075","article-title":"Fine structure of an intracerebral epithelial cyst.","volume":"41","author":"Ghatak","year":"1974"},{"key":"b9","series-title":"Arch Neurol Psychiatry","doi-asserted-by":"publisher","first-page":"391","DOI":"10.1001\/archneurpsyc.1935.02250140147013","article-title":"An ependymal cyst in the quadrigeminal region.
