YR 1977 UL http://tech.snmjournals.org/content/5/2/85.abstract AB A 4-month-old male infant with a diagnosis of progressive hydrocephalus since birth received a radionuclide brain scan using 99mTc-GHT. The study showed a very large posterior fossa with displacement of the transverse sinus. The diagnosis of a Dandy-Walker syndrome was substantiated by cerebral angiograms, pneumoencephalogram, and by axial tomography. Subsequent surgery proved difficult, with the ventriculoperitoneal shunt being placed and later removed. The shunt was then replaced and the infant’s condition and prognosis improved after the last surgical procedure.
