INTRODUCTION
Blockage of normal cerebrospinal fluid (CSF) pathways causing obstructive hydrocephalus is often a life threatening condition. If the site of obstruction is located around one of the foramen of Monro, an enlargement of one lateral ventricle will occur with or without periventricular CSF seepage depending upon the cause and this condition is called as unilateral hydrocephalus. Idiopathic unilateral foramen of Monro stenosis an uncommon cause of unilateral hydrocephalus without nearby secondary cause around the foramen of Monro. The clinical manifestations are mild or slowly progressive which often delayed the diagnosis of this entity.
So early imaging diagnosis of foramen of Monro stenosis is important for early surgical planning and neuroendoscopic approach for a successful treatment.
