The authors report the case of a 56-year-old previously healthy man who presented with a 4-month history of postural headache accompanied by nausea and vomiting. The results of initial imaging studies of the brain were normal. Repeated MR imaging demonstrated bilateral subdural hematomas which were drained and reaccumulated over a period of time. Spinal myelography revealed a cerebrospinal flui...

A double-blind study was conducted in 60 patients undergoing either cervical or more complete myelography via C1-C2 puncture. Patients received either iohexol or metrizamide at a 300 mg l/ml concentration. The contrast media were equally efficacious in the production of high-quality radiographs and CT scans. However, the incidence of adverse reactions differed markedly. Of patients receiving me...

A 74-year-old man developed proximal muscular weakness and wasting of the left upper extremity without sensory disturbance or myelopathic symptoms. The muscle atrophy had not progressed for a few years. Radiological examination of the spine showed cervical disc herniation. These findings and electrophysiological studies excluded motor neuron diseases, permitting the diagnosis of dissociated mot...

Injury to the cervical cord is common but may be overlooked The first important requirement in managing any patient with an injury to the cervical spine is to make the diagnosis: failure to do this in a patient with traumatic spinal instability may lead to increased neurological deficit. In one large series of such injuries the diagnosis was missed in the accident and emergency department in on...

We present a case of craniospinal hypotension in a 45-year-old woman with an associated epidural pseudomeningocele extending the entire length of the spine. The epidural pseudomeningocele was caused by a CSF leak at the T8 level. In addition to typical low-pressure symptoms, the epidural pseudomeningocele caused atypical symptoms characterized by positional thoracic radiculopathy. Craniospinal ...

Analysis of 200 cases reveals that the two neurological syndromes, brachial neuritis and myelopathy, associated with cervical spondylosis are distinct with relatively little overlap. While upper limb motor and sensory loss are doubtless due to nerve root compression in cases of "pure' brachial neuritis, they are more likely to be due to cord damage in cases with myelopathy (with spastic parapar...

A 27-year old man presented with a complaint of ‘difficulty in walking’. He had stiffness in the left upper and lower limb on walking, motivating him to sit down and rest after walking some distance. Prolonged grip of an object produced stiffness in his fingers. He also had slurring of speech, curiously also on walking. He was asymptomatic at rest. Distal arterial pulses were normal and there w...

Extraforaminal lumbar disk herniation is unusual and often undetected by myelography. Four cases were detected by high-resolution computed tomography. They were verified by surgery in one, diskography in one, and by the clinical course in two cases. Metrizamide myelography in two of the three patients was normal. This suggests that CT can accurately detect the diagnostically troublesome extrafo...

Lumbar myelography was performed in 50 patients; 25 received iohexol (an investigational aqueous contrast agent) and 25 received metrizamide. The two media produced radiographs of equal quality. However, iohexol is stable in solution, while metrizamide is not. Further, markedly less morbidity resulted from iohexol. These features indicate that iohexol may be superior to metrizamide as a contras...
