dilation of the third and both lateral ventricles In the hereditary cases reported by Bickers and Adams, the transmission was in three generations of males If the obstruction was in the fourth ventricle, the dilation included the aqueduct Other sites of obstruction of the CSF in the ventricular pathways are at the foramina of Luschka and Magendie (eg, congenital failure of opening of the foramina Dandy-Walker syndrome) More common is a blockage to ow of CSF in the subarachnoid space around the brainstem due to in ammatory or hemorrhagic brosing meningitis The latter forms of obstruction result in enlargement of the entire ventricular system, including the fourth ventricle A still useful adage, attributed to Ayer, is that the ventricle closest to the obstruction enlarges the most; meaning, for example, that occlusion of the basal CSF pathways causes a disproportionate enlargement of the fourth ventricle, and a mass within the fourth ventricle leads to a greater dilatation of the third than of the lateral ventricles Another potential obstruction site is in the subarachnoid spaces over the cerebral convexities A matter of considerable practical as well as theoretical interest is whether a meningeal obstruction over the convexities of the cerebral hemispheres, at the site of the arachnoidal villi, or a blockage of the venous sinuses into which the CSF is absorbed, can result in hydrocephalus Russell, in her extensive neuropathologic material and her review of the world s literature, could not nd a single well-documented example of either of these suggested etiologies, and the same is true of the pathologic material collected by our colleague RD Adams Moreover, experiments in animals in which all the draining veins had been occluded, a tension hydrocephalus with enlarging lateral ventricles was produced in only a few cases Yet Gilles and Davidson have stated that tension hydrocephalus in children may be due to a congenital absence or de cient number of arachnoidal villi, and Rosman and Shands have reported an instance that they attributed to increased intracranial venous pressure Our hesitation in accepting such examples stems from the dif culty that the pathologist has in judging the patency of the basilar subarachnoid space This is much more reliably visualized by radiologic than by neuropathologic means Theoretically, as mentioned earlier, if the obstruction is high, near (or in) the superior sagittal sinus, the CSF should accumulate under pressure outside as well as inside the brain, and the ventricles should not enlarge at all or only slightly, and only after a prolonged period The rarely encountered radiologic picture of enlarged subarachnoid spaces over and between the cerebral hemispheres coupled with modest enlargement of the lateral ventricles has been referred to as an external hydrocephalus Although such a condition does exist, many of the cases so designated have proved to be examples of sporadic or familial subdural hygromas or arachnoid cysts Processes such as subarachnoid hemorrhage and cerebral hemorrhage or brain abscess that rupture into the ventricles and rapidly expand the volume of CSF produce the most dramatic forms of acute hydrocephalus The obstruction of the CSF pathways will usually be found within the ventricular system or at the basal meninges The corresponding clinical syndrome of acute hydrocephalus is described below An increase in the rate of formation or decrease in the rate of absorption would be expected to cause an accumulation of CSF and increased ICP The only reported examples of overproduction of CSF are papillomas of the choroid plexus, but even in this circumstance there is usually an associated ventricular obstruction, either of the third or fourth ventricle or of one lateral ventricle.

As an anatomic entity, the basal ganglia have no precise de nition Principally they include the caudate nucleus and the lentiform nucleus with its two subdivisions, the putamen and globus pallidus Insofar as the caudate nucleus and putamen are really a continuous structure (separated only incompletely by bers of the internal capsule) and are cytologically and functionally distinct from the pallidum, it is more meaningful to divide these nuclear masses into the striatum (or neostriatum), comprising the caudate nucleus and putamen, and the paleostriatum or pallidum, which has a medial (internal) and a lateral (external) portion The putamen and pallidum lie on the lateral aspect of the internal capsule, which separates them from the caudate nucleus, thalamus, subthalamic nucleus, and substantia nigra on its medial side (Figs 4-1 and 4-2) By virtue Table 4-1 Clinical differences between corticospinal and extrapyramidal syndromes

of their close connections with the caudate and lenticular nuclei, the subthalamic nucleus (nucleus of Luys) and the substantia nigra are usually considered as parts of the basal ganglia The claustrum and amygdaloid nuclear complex, because of their largely different connections and functions, are usually excluded For reasons indicated further on, some physiologists have expanded the list of basal ganglionic structures to include the red nucleus, the intralaminar thalamic nuclei, and the reticular formations of the upper brainstem These additional structures receive direct cortical projections and give rise to rubrospinal and reticulospinal tracts which run parallel to the corticospinal (pyramidal) ones; hence they were also once referred to as extrapyramidal However, these nonpyramidal linkages are structurally independent of the major extrapyramidal circuits that include the striatum, pallidum, thalamus, and premotor and supplementary motor cortices Insofar as the nal links in this circuit the premotor and supplementary motor cortices ultimately project onto the motor cortex, the aforementioned circuit is more aptly referred to as prepyramidal (Thach and Montgomery) Earlier views of basal ganglionic organization emphasized the serial connectivity of the basal ganglionic structures and the funneling of efferent projections to the ventrolateral thalamus and thence to the motor cortex (Fig 4-3) This concept was based largely on the classic experimental work of Whittier and Mettler and of Carpenter, in the late 1940s These investigators demonstrated, in monkeys, that a characteristic movement disorder, which they termed choreoid dyskinesia, could be brought about in the limbs of one side of the body by a lesion localized to the opposite subthalamic nucleus They also showed that for such a lesion to provoke dyskinesia, the adjacent pallidum and pallidofugal bers had to be preserved; that is, a secondary lesion placed in the medial segment of the pallidum, in the fasciculus lenticularis, or in the ventrolateral thalamic nuclear group abolished the dyski-.
