In each case a well-developed subarachnoid space was present and in no cases were the leptomeninges congenitally absent. Thus, the commonly held belief that the subarachnoid space may fail to develop in congenital obstructive hydrocephalus was not supported by this study. Pathological findings in the leptomeninges were common, however, and were generally related to the following factors: the severity of the hydrocephalus, the duration of the hydrocephalus, the success or failure of surgical management, past infection (both intrauterine and postnatal), and subarachnoid hemorrhage. The type of ventricular obstruction did not seem to be a significant factor. Certain embryological considerations raised by the current findings are discussed.<\/jats:p>","DOI":"10.3171\/jns.1971.35.1.0007","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T14:35:54Z","timestamp":1241706954000},"page":"7-15","source":"Crossref","is-referenced-by-count":18,"title":["The subarachnoid space in congenital obstructive hydrocephalus"],"prefix":"10.3171","volume":"35","author":[{"given":"Thomas H.","family":"Milhorat","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mary K.","family":"Hammock","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roma S.","family":"Chandra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Introduction to Neuropathology.","first-page":"84","author":"Adams","year":"1968"},{"key":"b2","series-title":"Correlative Anatomy of the Nervous System.","first-page":"576","author":"Crosby","year":"1962"},{"key":"b3","series-title":"Practice of Surgery.","article-title":"The brain","author":"Dandy","year":"1932"},{"key":"b4","series-title":"Pathology of the Nervous System.","first-page":"77","article-title":"Embryogenesis of the nervous system","author":"Duncan","year":"1968"},{"key":"b5","series-title":"Neuropathology.","first-page":"312","author":"Greenfield","year":"1958"},{"key":"b6","series-title":"Neurology.","first-page":"214","author":"Grinker","year":"1960"},{"key":"b7","series-title":"Proc Roy Soc Med","doi-asserted-by":"publisher","first-page":"1264","DOI":"10.1177\/003591576706001208","article-title":"Hydrocephalus: radiological diagnosis in infancy.","volume":"60","author":"Hoare","year":"1967"},{"key":"b8","series-title":"Neurosurgery of Infancy and Childhood.","first-page":"117","author":"Ingraham","year":"1954"},{"key":"b9","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"313","DOI":"10.3171\/jns.1967.26.3.0313","article-title":"Long-term results in various treatments of hydrocephalus.","volume":"26","author":"Jones","year":"1967"},{"key":"b10","series-title":"Pathology of the Nervous System.","first-page":"456","article-title":"Hydrocephalus","author":"Klosovsky","year":"1968"},{"key":"b11","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"673","DOI":"10.3171\/jns.1969.30.6.0673","article-title":"Evaluation of photoscanning of the diffusion of intrathecal RISA in infantile and childhood hydrocephalus.","volume":"30","author":"McCullough","year":"1969"},{"key":"b12","series-title":"J.
