In a retrospective study of magnetic resonance (MR) images obtained in 289 neurosurgical patients, loss of signal intensity (signal-void phenomenon, SVP) of the cerebrospinal fluid (CSF) in the mesencephalic aqueduct was observed in 77 patients. This SVP was noted in the MR studies of 12 of 14 patients with communicating hydrocephalus who showed a normal mean intracranial pressure (ICP) and normal pulse pressure, but in only seven of 50 patients with high mean ICP and high pulse pressure (such… CONTINUE READING
