A 62-year-old man was admitted for right arm radicular pain and diplopia. Eight months earlier he had documented metastatic adenocarc inoma, primary site unknown, with pleural and skeletal involvement. On physical examinat ion, he was alert, well oriented, and afebrile. Pertin ent findings included a supple neck, a left sixth cran ial nerve palsy with questionable left retinal mass, and mild we...

Spontaneous intracranial hypotension (SIH) is a condition caused by spontaneous cerebrospinal fluid (CSF) leakage, resulting in orthostatic headache as the main symptom, but other symptoms such memory loss, nausea, and tinnitus may also be present. Various imaging techniques are used to diagnose SIH, with magnetic resonance myelography being an important tool for detecting leakage site of CSF. ...

A programmed investigation unit (PIU) was set up in a regional neuroscience centre. Its effects were assessed by measuring the savings associated with one particular investigation, myelography, which accounted for 50% of admissions to the PIU. Substantial savings appear to be possible, but accounting techniques allow wide variations in the estimated amounts. These benefits have to be measured a...

An article by Dr. H. L. Feffer, in Medical World News in September, 1978 entitled Arachnoiditis Risk After Myelography, suggested that the at least a quarter of patients undergoing a myelogram (400,000 then being performed every year in the US) develop iophendylate arachnoiditis and furthermore, that those undergoing two or more myelogram studies have a 50% chance of developing iatrogenic arach...

Study Design Case report. Objective Describe a case of intradural disk herniation and a method for intraoperative localization. Methods Intradural disk herniations are uncommon but well described. The diagnosis of these lesions is often difficult, and sometimes they may be diagnosed only through an intradural exploration after an expected disk fragment cannot be located. We report the case of a...

BACKGROUND Conventional magnetic resonance imaging (MRI) of complex cervical spine disorders may underestimate the magnitude of structural disease because imaging is performed in a nondynamic non-weight-bearing manner. Myelography provides additional information but requires an invasive procedure. METHODS This was a prospective review of the first 20 upright weight-bearing cervical MRI proced...

The use of MR imaging in the evaluation of spinal tumors has been well documented [1-4]. Once a mass is recognized , images in multiple planes and multiple signal sequences are used for better definition, especially of its location. For the most part, the same neuroradiologic criteria used in CT, conventional myelography, and CT-myelography are used for this purpose. This report describes a new...
