We present a patient in whom dysphasia followed suddenly upon an apparently discrete thalamic infarct proven by computed tomography (CT). Detailed psychometric data of the patient's speech and memory disorder obtained during the acute and chronic stages were correlated with the evaluation of a focal thalamic lesion as demonstrated by serial CT. The findings(More)
Twenty-seven cancerous larynges were examined preoperatively by computed tomography and postoperatively by transaxial anatomic sections. Data from this correlative study provides a new radiographic classification based upon the relationship of the plane of maximal tumor size to the apex, body, or vocal process of the arytenoid. Unlike those tumors whose(More)
A four-stage model of pain processing was proposed, consisting of pain sensation intensity, pain unpleasantness (stage 1 affect), suffering (stage 2 affect), and pain behavior. We studied 506 chronic pain patients (230 male and 276 female) using a multivariate statistical technique (LISREL) in order to demonstrate the structural relationship among multiple(More)
Progressive left hemiparesis followed by face and trunk cutaneous vasodilation and hyperphagia developed in a 28-year-old man. He began eating five to six meals a day and gained 16 kg in 60 days. Computed tomography disclosed a neoplastic lesion involving the midline via the hypothalamus and reaching the contralateral lenticular nucleus. Findings from(More)
Detailed anatomic analysis of the human temporal bone has been made possible by correlating high-resolution computed tomography (CT) with gross anatomic sections. Serial CT scans of isolated temporal bones were obtained in the transaxial (horizontal), coronal, and sagittal planes at 1.5-mm intervals. The temporal bone was sectioned at 2.0-mm intervals in(More)
The surgery of hyperparathyroidism can be technically very difficult, even for an experienced surgeon. Until the present decade, preoperative localization procedures were of little help because of poor resolution of imaging modalities, significant morbidity, and the cost of invasive procedures. The efficacy of preoperative high-resolution CT scanning was(More)
A study of the findings on cisternograms and computerized transaxial tomography (CTT) of 144 patients showed good correlation between the two tests. Patients with a cisternographic pattern of communicating hydrocephalus tended to show more severe degrees of lateral ventricular dilation, with involvement of the third and fourth ventricles and relative(More)
A 72-year-old woman, blind for more than two years, had normal evoked potentials to visual stimulation. Destruction of both areas 17 and relative preservation of areas 18 and 19 was demonstrated. We concluded that in the presence of bilateral destruction of area 17, visual evoked potentials are mediated by extrageniculocalcarine pathways to secondary visual(More)
A 48-year-old laborer presented with a 1-year history of low-back pain radiating into the posterior aspects of both thighs. Two weeks before admission, acute exacerbation resulted in signs and symptoms of compressive radiculopathy at L-5. Myelography revealed concentric constriction of the lower thecal sac due to abundant fat, as shown by computerized(More)
