Massive ventricular enlargement, in a patient with normal social
(A) CT; (B, C) T1-weighted MRI, with gadolinium contrast; (D) T2-
weighted MRI. LV=lateral ventricle. III=third ventricle.
IV=fourth ventricle. Arrow=Magendie's foramen. The posterior
fossa cyst is outlined in (D).
His neurological development and medical history were otherwise
normal. He was a married father of two children, and worked as a
civil servant. On neuropsychological testing, he proved to have
an intelligence quotient (IQ) of 75: his verbal IQ was 84, and
his performance IQ 70. CT showed severe dilatation of the
lateral ventricles (figure); MRI revealed massive enlargement of
the lateral, third, and fourth ventricles, a very thin cortical
mantle and a posterior fossa cyst. We diagnosed a non-
communicating hydrocephalus, with probable stenosis of
Magendie's foramen (figure). The leg weakness improved partly
after neuroendoscopic ventriculocisternostomy, but soon
recurred; however, after a ventriculoperitoneal shunt was
inserted, the findings on neurological examination became normal
within a few weeks. The findings on neuropsychological testing
and CT did not change.
