The surgical and computerized tomographic myelography (CTM) features of 134 stenotic foraminal canals were correlated retrospectively in 95 patients. The myelographic site of stenosis was the entrance to the foraminal canal in 70 cases (52%) and the canal itself in 37 (28%); the site was not identified definitively in 27 (20%). At the entrance to the(More)
The authors present the case of a 22-year-old woman who developed spontaneous intracranial hypotension as a result of a cerebrospinal fluid leak from a thoracic extradural arachnoid diverticulum. The patient was successfully treated by ligation of the diverticulum. The entity of spontaneous intracranial hypotension and its relevance to neurosurgery are(More)
Phrenic neuropathy associated with brachial neuritis has been well described; however, bilateral phrenic neuropathy with minimal or no involvement of the brachial plexus has not. We review the clinical features, as well as the results of radiographic studies, pulmonary function tests, and electrodiagnostic studies, of 3 patients in whom dyspnea was the(More)
One hundred forty-one patients with cerebral or cerebellar infarction were examined by computed tomography (CT) as soon after the ictus as possible. The examination was repeated in 7 days, and a radionuclide brain scan was performed. The overall detection rate for ischemic infarction was approximately equal for both techniques, ranging from 58% for(More)
One hundren patients underwent high-resolution dynamic ultrasound imaging of the carotid bifurcation immediately before cerebral angiography. The examinations were interpreted independently. A positive ultrasound interpretation indicated the presence of moderate to extensive atheromatous plaque, while a negative interpretation indicated normal vessels or(More)
OBJECTIVE To determine which components of cervical spondylosis are most frequently present in patients with myelopathy. DESIGN We reviewed the findings in 93 patients who underwent surgical decompression for cervical spondylotic myelopathy between January 1986 and December 1989 at Mayo Clinic Rochester. MATERIAL AND METHODS All 93 patients (72 men and(More)
The accuracy of ophthalmodynamometry and ocular pneumoplethysmography for predicting pressure-significant lesions of the internal carotid system was compared in a series of 119 consecutive patients (210 arteries) having cerebral angiography. Overall accuracy (92.5%) for ocular pneumoplethysmography was significantly better than that for ophthalmodynamometry(More)
In three survivors of central pontine myelinolysis, dystonia (in two patients) and rest tremor (in one) were sequelae. The onset of these movements occurred 3 weeks to 5 months after the initial presentation with central pontine myelinolysis. Magnetic resonance imaging revealed basal ganglia lesions suggestive of extra-pontine myelinolysis in all three(More)
Intravenous digital subtraction angiography (IV-DSA) and subsequent conventional selective carotid angiographic examinations were reviewed in 78 patients who were suspected of having cerebrovascular disease, and the results were correlated with surgical findings in 53 patients. The impact of the information provided by each of these examinations on(More)
Ocular pneumoplethysmography and ophthalmodynamometry measure ophthalmic arterial system pressures to assess noninvasively the hemodynamics of the carotid system. A previously unreported circumstance in which these tests complement one another is central retinal artery occlusion. Typically, the ipsilateral retinal artery pressure, measured by(More)
