Spontaneous resolution of acute hydrocephalus without aspiration of cerebra
l fluid is rare. In a neonate born at full term this has only been reported
once before. We report on one further case that was caused by intraventric
ular haemorrhage (IVH). The probable mechanism is resolution of the acute h
aemorrhage in the region of the aqueduct, resulting in resolution of the hy
drocephalus itself. The importance of considering conservative management o
f acute hydrocephalus in the clinically stable neonate is emphasised.
