Delayed Posttraumatic Hydrocephalus Secondary To An Aqueductal Web Treated With Endoscopic Third Ventriculostomy: A Case Report.

Abstract

BackgroundDelayed posttraumatic hydrocephalus is typically communicating secondary to arachnoid villi insufficiency, due to a reactive inflammatory response to blood products. Acute obstructive hydrocephalus secondary to an aqueductal clot or midbrain contusion has been published; however, no previous publications of delayed obstructive posttraumatic hydrocephalus have been found. Case descriptionWe present a case report of delayed obstructive hydrocephalus secondary to an aqueductal web. The patient was successfully treated by an endoscopic third ventriculostomy. ConclusionTo our knowledge, this is the first description of delayed obstructive posttraumatic hydrocephalus secondary to an aqueductal web, and we discuss the pathophysiological cause, and relevant treatment options.
