Computed tomography (CT) has made a profound impact on the diagnosis and treatment of neuroblastomas and ganglioneuromas. The size, location, calcification, composition, and contiguous spread of the tumors has been well demonstrated by CT. CT is essential for their staging, subsequent treatment, and follow-up. Seventy-seven children were reviewed, 67 with neuroblastoma and 10 with ganglioneurom...

Within 20 months 145 ascending thoracocervical myelographies and 155 lumbar myelographies with the nonionic water-soluble contrast medium iopamidol were performed. The iodine concentration given was 250 mg I/ml or 200 mg I/ml respectively. The total iodine never exceeded 2.5 g (8-10 ml). Image quality was assessed in terms of diagnostic value having experience of more than 1,000 myelographies u...

Birth trauma to the spinal cord is a serious potential complication of delivery. Determining the presence, severity, and extent of injury poses a difficult problem because of the often confusing clinical setting. Myelography has been recommended for assessing spinal cord birth trauma but is invasive and may not be helpful. The role of sonography in evaluating spinal cord birth trauma has not be...

Herniation of the spinal cord through a dural rent is a rare occurrence. Although sporadic cases have been documented, the diagnosis has never been made preoperatively [1 -3J . We report a case of a transdural cord herniation at the C1 C2 level. The dural tear was a result of penetration by a broken fracture-fi xation wire and its subsequent complications. Transdural spinal cord herniation was ...

Perineurial cysts may be responsible for clinical symptoms and a cure effected by their removal. They do not fill on initial myelography but may fill with Pantopaque some time, days or weeks, after Pantopaque has been instilled into the subarachnoid space. Perineurial cysts arise at the site of the posterior root ganglion. The cyst wall is composed of neural tissue. When initial myelography fai...

Diastematomyelia is an uncommon dysraphic lesion of the spine which has been diagnosed more frequently since the advent of newer diagnostic methods. A series of 21 cases was examined using metrizamide myelography and computed tomographic metrizamide myelography (CTMM) over a 3-year period. These examinations, in addition to plain radiographs of the spine, have demonstrated certain features of d...

BACKGROUND Patients with chronic postural headaches may suffer from spontaneous intracranial hypotension (SIH). Trauma, degenerative disc spurring and connective tissue disorders are documented risk factors; in most cases there is no inciting event. Despite sophisticated means of evaluating the neuraxis, many cerebrospinal fluid (CSF) leaks are radiographically occult and treatment is focused o...

Meningiomas are the most common primary tumours of the canine central nervous system. The incidence of these tumours increases with age and they are more frequently encountered in dogs older than seven years. Meningiomas are solitary, well-defined neoplasias that more commonly grow via compression and less commonly by infiltrating the nervous tissue. Meningiomas exhibit 82% intracranial, 15% in...

STUDY DESIGN Single-center retrospective study. PURPOSE To clarify the clinical features of cervical myelopathy at the C1-2 level. OVERVIEW OF LITERATURE Methods for distinguishing the affected level based on myelomere symptoms or dysfunction of the conducting pathway were established. However, no symptoms have been identified as being specific to the C1-2 level segment. METHODS We evalua...
