Spontaneous ventriculostomy is a rare condition that occurs with the sponta
neous rupture of a ventricle, resulting in a communication between the vent
ricular system and the subarachnoid space. Three cases of spontaneous ventr
iculostomy through the floor of the third ventricle that occurred in cases
of chronic obstructive hydrocephalus are presented. The communication was i
dentified via flow-sensitive phase-contrast cine MR imaging. Spontaneous ve
ntriculostomy is probably a result of a rupture of the normally thin membra
ne that forms the floor of the third ventricle and, with long-standing obst
ructive hydrocephalus, creates an internal drainage pathway that spontaneou
sly compensates for the hydrocephalus.
