In 1973 we reported results of ventricular shunting in 28 patients with idiopathic normal pressure hydrocephalus. The present report consists of a three year follow-up of the latter (series 1), and an additional 45 patients (series 2) are presented for further insight into the conclusions drawn from the original experiences.
Although cerebellar infarction was known at the turn of the century, not until 1956 was it realized that large cerebellar infarctions could cause acute obstructive hydrocephalus. There are many more reports of cerebellar hemorrhages. The clinical differentiation between hemorrhage and infarction was difficult prior to computerized tomography (CT).… (More)
Eleven cases of enlarged cisterna magna were found in a series of 3000 computerized tomography scans. We believe mega cisterna magna by itself is not related to any specific symptoms and may not require further study or treatment.
Thirty-three patients suspected of having a seizure disorder had routine electroencephalograms (EEG's) followed by post-sleep deprivation (P-SD) EEG's. The P-SD EEG's revealed abnormalities in 33% of those patients with a normal routine EEG. All of those patients with P-SD activation had histories highly suggestive of a seizure disorder. Most patients with… (More)
For several years, some sectors of the specialty of Radiology have complained about the practice of self-referral, where a nonradiologist physician provides and interprets an imaging procedure. It is argued that such practice leads to increased costs since a physician will overutilize technology because of financial incentives. Here we review the… (More)
Intracerebral hemorrhage has been thought in the past to be manifested by sudden onset of hemiplegia, severe headache and deep coma proceeding to death in most cases. There are patients who present with less ominous symptoms who have heretofore been though to have cerebral infarction or transient ischemic attacks who in reality have intracerebral… (More)
Neuroimaging of the spinal cord has taken on new dimensions in the past few years. With improvement in surface coils, elimination of artifacts, and fast scan imaging, myelography with all of its complications is on the wane. Computerized tomography is excellent for bony abnormalities, but most patients with spinal disease can be diagnosed with magnetic… (More)
Seven of eight patients had a clinical diagnosis other than brainstem hemorrhage before computed tomography (CT). Four were diagnosed as infarction, one as intracerebral hemmorrhage, one as hypertensive encephalopathy, and one as subdural hematoma. All survived except one, who died of pulmonary embolus. Although the yeild of posterior fossa lesions on CT is… (More)
