Role of computerized tomographic cisternography in idiopathic normal pressure hydrocephalus.

Background: We prospectively evaluate the role of computerized tomographic cisternography (CTC) in idiopathic normal pressure hydrocephalus (iNPH).

Methods: The cerebrospinal fluid kinetics of 70 patients who passed the entry criteria for the Study of iNPH on Neurological Improvement (SINPHONI) and underwent insertion of a shunt were studied.

Results: Stasis of the contrast medium at the lateral ventricles over 24 h (positive ventricular stasis) was observed in 60 patients and at the Sylvian fissure or parietal sulci over 48 h (positive surface stasis) in 59 patients.

A recurrent intradural cervical neurenteric cyst operated on using an anterior approach: a case report.

The neurenteric cyst is an uncommon congenital lesion. In most reported cases, it has been operated on via a posterior approach using a laminectomy, despite the fact that the cyst is usually located ventral to the spinal cord. Reports have shown that early postoperative results have been good with the posterior approach, but very few studies of the long-term postoperative recurrence of neurenteric cysts have been conducted.
