✓ A case of supratentorial intracerebral cyst, containing ectopic choroid plexus, is discussed. The cyst had no communication with the ventricular system or subarachnoid space. The cyst wall was lined in part by flattened or cuboidal epithelium and in part by glia. Fronds of choroid plexus protruded into the cavity of the cyst in one part. The preoperative and postoperative computerized tomography scans are presented and the operative findings are discussed. The management of such cases is reviewed.

✓ The authors report an adult patient with a symptomatic interhemispheric cyst demonstrated by computerized tomography (CT), angiography, and at surgery. Choroid plexus epithelium was identified arising from the inner aspect of the cyst wall. Partial agenesis of the corpus callosum is postulated on the basis of the CT findings and the presence of choroid plexus in the interhemispheric cyst.

✓ Two patients with benign intracerebral cysts are reported and a brief review of the literature is given. Although computerized tomography (CT) scanning is useful in detecting a variety of intracerebral cysts, the CT findings are not specific for any lesion. An exploratory operation with establishment of an adequate route of drainage and a histological examination of the cyst wall are mandatory in the management of patients with a progressive but benign lesion.

✓ Cats were made hydrocephalic by cisternal instillation of kaolin. Three to 8 weeks later it was found by perfusion between the ventricular system and the spinal subarachnoid space that communication had been reestablished through a demonstrably dilated central canal of the spinal cord. Absorption of fluid from the ventricular system, measured both by ventriculospinal perfusion and, after ligation of the spinal cord, by perfusion between the lateral ventricles, was found to be indistinguishable from zero over a wide range of ventricular pressure.

✓ A large subdural xanthogranuloma was removed from the posterior fossa of a 53-year-old woman with symptoms of Hand-Schüller-Christian disease. Two additional masses with similar density on computerized tomography were found in the hypothalamus and in the choroid plexus of the right lateral ventricle.

✓ This study reports six cases of hydrocephalic children with the “slit ventricle syndrome” who evidenced reexpansion of the ventricular system following insertion of high-resistance valves and anti-siphon devices. The authors contend that slit ventricles and subsequent ventricular coaptation can be prevented by elimination or early replacement of low-resistance valves, and maintenance of normal- or nearly normalsized ventricles by shunt revision with valve upgrade and/or an anti-siphon device, as judged by the appearance of the ventricles on computerized tomography.

✓ Choroid plexus blood flow (CPBF) and glucose utilization (CPGU) were measured in two groups, each of seven identically prepared, unanesthetized rats, using complementary quantitative autoradiographic techniques. Both CPBF and CPGU were lowest in the lateral ventricles (0.83 ± 0.01 ml · g−1 · min−1 and 0.70 ± 0.02 µmoles · g−1 · min−1, respectively) and highest in the fourth ventricle (1.56 ± 0.05 ml · g−1 · min−1 and 1.39 ± 0.05 µmoles · g−1 · min−1, respectively). Despite this heterogeneity, the proportionate relationship between CPBF and CPGU was relatively constant throughout the ventricular system. This suggests that blood flow and metabolism may normally be coupled in the choroid plexus, and that the choroid plexus of the fourth ventricle may account for a disproportionate share of the functional activity of this tissue.

✓ Newborn hamsters and kittens infected with vaccinia virus developed communicating hydrocephalus without fibrotic changes in the meninges. Following intracerebral viral inoculation, a transient inflammation of the meninges, ependyma, and choroid plexus was found. One month later, 70% of hamsters infected with the WR strain of vaccinia virus and 35% infected with the vaccine strain developed hydrocephalus. The mechanism of hydrocephalus production is unclear, but differs from other models in which it is associated with stenosis of the aqueduct of Sylvius or fibrosis of the subarachnoid space.

✓ Four patients with tentorial arteriovenous malformations (AVM's) were treated surgically. The operative findings in the first case suggested that clipping of the draining vein close to the AVM may result in complete cure. The three subsequent cases were treated with this technique. The clinical and radiological implications are discussed.
