Niopam is a newer, nonionic, watersoluble contrast medium used predominately in cisternographic and myelographic studies with metrizamide lately. The former has fewer, less severe and shorter adverse reactions than the latter. Until now there were no reports on meningitis complicating Niopam CT cisternography or myelography. Now we present a case of aseptic purulent meningitis complicating Niopam CT cisternography.

In a comparative, prospective randomized study 200 patients underwent myelography using iopamidol (150 patients) or metrizamide (50 patients) as contrast medium. Adverse reactions were few, mild, and short in duration in iopamidol myelography compared to metrizamide myelography. Seizure occured in 2 patients with the use of metrizamide. Iopamidol appears to be superior to metrizamide for intrathecal administration.

Metrizamide lumbar myelography were performed in 150 patients with suspected herniated lumbar disc. The examination is easier to perform than with gas or iophendylate. The advantage of metrizamide over gas or iophendylate are the improved root sleeve visualization and examination of small structure such as root, root pocket and blood vessel. And then this is a higher percentage of diagnostic accuracy than can be obtained with other myelogram. Most of adverse reactions during and after myelography are mild and transitory, and no serious adverse reactions occured. It probably has a lower neurotoxicity than any other water soluble contrast agent.

Intraventricular cysticercosis is the rest form of cerebral cysticercosis and almost all are within the fourthand third ventricles. Authors have experienced a case of pathologically proven giant intraventricular cysticercalcyst involving the lateral ventricle, studied by conventional CT and metrizamide CT, and report with brief reviewof literature.

Intrathoracic meningocele is a protrusion of the spinal meninges through an intervertebral foramen into thethoracic cavity. The majority occur in association with neurofibromatosis. The authors experienced a case ofintrathoracic meningocele in 26 years old male patient associated with neurofibromatosis, and present conventional CT and CT metrizamide myelographic findings.

Eleven cervical myelograms were perfomed by lateral cervical puncture using Metrizamide. So, following resultswere obtained: 1. Site of lateral cervial puncture; Posterior one third of bony cervical canal at C 1-2 level. 2.Advantages as compared with lumbar puncture for cervial myelogram; 1) Small amount of contrast media 2) Excellentimage 3) Less position change 4) Short time 5) Well visualization of superior margin of obstructive lesion inspinal canal 3. Cessation of lateral cervical puncture, when; 1) Pain during injection of contrast media 2)Localized collection of contrast media

In lumbar myelography many side effects occurs in about half the patients examined with modern contrast media. We used amipaque, water soluble contrast media for lumbar myelography in 14 patients with herniated lumbar disc. At myelography with amipaque the side effects are usually minor and serious adverse reactions are rare. Amipaque is of greatest advantage in examination of small structures such as roots, root pockets and blood vessels in spinal subarachnoid space.

One case of far lateral lumbar disc herniation(FLLDH) at left L5-S1 intervertebral space is reported. The herniation of disc material was localized mainly beyond the intervertebral foramen. Metrizamide myelogram was normal and only spine CT scan revealed the protruded disc material compressing the upper root inside and outside of the intervertebral foramen. Accordingly, the presenting symptoms and signs were due to left L5 root compression. Facetectomy was followed by removal of the herniated disc material. The patient was improved well.

A total 48 cases of myelography using Metrizamide were performed between August 1981 and July 1983 at the department of Orthopedic Surgery, Kwangju Christian Hospital. Of these cases, H.N.P was 26, tuberculous spondylitis 16, spondylolisthesis 4, and multiple sclero-sis 2 cases. The advantages of this study were as folows: 1. Complications were minimal in most of the cases except a slight headache. 2. Large amount of infusion was possible. 3. Rootlet was clearly seen. 4. Removal of dye was not necessary. 5. It gave a good contrast for the radiologic study.

CT and myelography, separately or combined together, have been used for the study of spine lesion. Metrizamide enhanced CT is a new diagnostic modality for the study of spine lesion. The purpose of this study was to compare the efficacy of metrizamide enhanced CT with those of CT and metrizamide myelography. Among 163 surgically proven cases, metrizamide CT was carried out on 49 cases, CT on 50 cases and myelography on 64 cases, at Department of Orthopedic Surgery, Seoul University Hospital for 3 years period from August 1981 to July 1984. 1. Overall diagnostic accuracy of CT was 90%, that of metrizamide myelography was 82.8%and that of metrizamide CT was 93. 9%. 2. Diagnostic accuracy of metrizamide CT in HIVD was 95%, in spinal stenosis 94.4% and in spondylolisthesis 80%. 3. Most of complications were observed in myelography, even they were minor. 4. It was concluded that plain CT was advisable on a clinically typical HIVD, considering complications and expenses of myelography and metrizamide CT. 5. Metrizamide CT was indicated on previously operated cases or atypical HIVD, spinal stenosis and spondylolisthesis.
