25 year old patient presented with headache and
vomitting of few days duration. MRI showed
obstructive hydrocephalus with dilatation of all the
ventricles and ballooned out fourth ventricle.
This was suggestive of fourth ventricular outlet
obstruction. The patient underwent Endoscopic Third
Ventriculostomy to relieve the obstruction. Patient
recovered well and follow up CT shows completely
decompressed fourth ventricle.
Endoscopic third ventriculostomy (ETV) is a very good
surgical method to relieve obstructive hydrocephalus.
It avoids the need of shunt and its associated problems.
