Spontaneous Ventriculostomy into the Subdural Space in a Neonate with Congenital Hydrocephalus

Abstract

We report a case of spontaneous temporary resolution of congenital hydrocephalus due to drainage into the subdural space, which is not a physiological space for cerebrospinal fluid (CSF). This is the first report of spontaneous drainage of CSF into the subdural space, and we term it “ventriculosubdurostomy.” We highlight the fact that spontaneous resolution of hydrocephalus due to drainage into a nonphysiological CSF space is temporary.

Spontaneous external rupture of hydrocephalus after fontanelle closure: a case report and review of literature

“…If the pathologic process goes without intervention for long, it may lead to some odd complications like ventricular diverticulum [ 6 ] and even ventricular rupture. A few cases with internal rupture of enlarging ventricles into cisternal spaces or subdural space [ 7 – 9 ] and external rupture through the patent anterior fontanelle presenting with CSF leak with or without meningitis have already been reported in the literature (Table 1 ) [ 1 – 4 , 10 , 11 ]. Out of the 6 other cases of external rupture described in the literature, 2 were associated with lumbosacral myelomeningocele [ 2 , 3 ] and in other 3, congenital aqueductal stenosis [ 1 , 4 , 10 ] was the cause of hydrocephalus while it was not mentioned in one.…”
