Delayed ischaemia due to vasospasm after fenestration of a large arachnoid cyst

Abstract

An 18-year-old patient developed multiple infarcts, nine days after endoscopic fenestration of a large arachnoid cyst. We consider vasospasm to be the most likely cause, presumably triggered by a chemical meningitis. Although mostly seen after subarachnoid haemorrhage, vasospasm can also occur after traumatic brain injury, brain surgery or meningitis.

Cerebral Vasospasm after Open Fenestration of an Arachnoid Cyst in a 4-Year-Old Boy: Case Report and Review of the Literature

“…To our knowledge, CVS after fenestration of an arachnoid cyst has only been reported once in an adult patient [12]. Pediatric cases of nonaneurysmal, non-TBI vasospasm have been reported following open tumor resection [13-16] and administration of certain chemotherapies [17, 18] (Table 1).…”
