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 ...

Computed tomography with and without administration of intrathecal contrast material was evaluated in 100 patients with suspected lumbar disk disease. Metrizamide computed tomography was performed in 75 patients and plain computed tomography was performed in 25. Metrizamide computed tomography was more accurate than plain computed tomography. It also disclosed many lesions not shown by metrizam...

Doubt remains as to the safest surgical approach to the prolapsed thoracic intervertebral disc. Laminectomy, lateral rhachotomy and the transthoracic approach all have their protagonists. Twenty-two patients from the National Hospital for Nervous Diseases, Queen Square, and Atkinson Morley's Hospital have been reviewed. Their clinical presentation is discussed and the ancillary aids to diagnosi...

Myelography was performed in 16 monkeys using either metrizamide or iohexol, a new nonionic aqueous contrast medium. Eight of the animals received almost five times the recommended clinical dose of contrast medium per unit of body weight; the other eight received the equivalent of a high clinical dose. The severity of resultant arachnoiditis 12 weeks later was evaluated by repeat myelography an...

Spine vascular lesions like brain include spinal cord stroke, malformation such as venous or angioma, cavernous malformation, arteriovenous fistula. Embryogenesis of is the basic principle to understand spine. This study aims report serial cases with review lesions. MR angiography techniques contrast injection may reflect direction flow epidural veins describe site arterial feeders. Serpiginous...

Plain computed tomography (CT) of the lumbosacral spine may be a reliable method for diagnosing herniated disk when abundant epidural fat is present. When epidural fat is not sufficient, CT after the administration of nonionic contrast medium (170 mg I/ml) and/or regular metrizamide myelography have been used. Ten patients were studied by CT enhanced with air injected as a negative contrast age...

Spinal meningeal cysts in the sacrum (SMC) are known to be occasionally symptomatic with low back pain as well as leg pain, but no distinct prevalence of this pathological entity including asymptomatic lesions has been described. This prospective study investigated the prevalence of SMCs based on magnetic resonance (MR) myelography in 102 consecutive Japanese women with gynecological problems, ...

AIM To point out the similarity of Meniere disease and spontaneous intracranial hypotension and difference of their treatment. METHODS A case of a 54-year-old male patient with previously diagnosed Meniere's disease and newly diagnosed spontaneous intracranial hypotension syndrome is presented. Additional neuroradiological examination, Brain contrast-enhanced MRI and MR myelography were used ...

We report on a case of a mobile schwannoma of the cauda equina. The patient was a 24-year-old woman who visited our hospital with the chief complaints of low back pain and numbness of the right leg. A tumor was noted from the L2 midbody level to the L3 upper endplate on preoperative MRI and myelogram. During the surgery, a right L2 hemilaminectomy was performed, and the dura was incised, but no...

A retrospective study was devised to determine the correlation between myelography and computed tomography (CT) in the recognition of abnormalities of the lumbar intervertebral disk. A group of 106 patients was studied who had had both myelography and CT within a 6 week period. Each examination was interpreted separately by a neuroradiologist who had no access to the patients' clinical findings...
