Vascular lesions, identical in appearance with the sequelae of organic diseases of the blood-vessels, have been found in a great variety of conditions (for instance in epilepsy, hypertension and cardiac disease, psychoses associated with infectious and toxic conditions, head injuries, certain groups of mental deficiency) in which no organic lesion of the blood-vessels themselves could be demonstrated. The theory has been put forward (Ricker, Spielmeyer and others) that these lesions owe their origin to functional disorder of the vascular system, and that this common factor accounts for the identity in histological appearance in spite of the profound ætiological differences.

AbstractABR were recorded in 68 cases suffering from severe acute closed head injuries. Abnormal recordings were observed in 60 per cent of patients, and the abnormalities ranged from prolongation of the interpeak latency intervals to complete absence of auditory brain stem activity. Based on the results obtained, a grading system was developed and correlated with the neurological outcome. It was concluded that ABR is a useful diagnostic and prognostic tool which can provide valuable information about the function of the brain stem in these patients. Inclusion of ABR studies in the head injury management protocol is strongly recommended.

Supratentorial Mass

✓ The neurological status and supra- and infratentorial intracranial pressures were studied in awake unsedated cats during expansion of a supratentorial mass. The pontomesencephalic portion of the brain stem was removed, serially sectioned, stained with sodium nitroprusside benzidine, and microscopically examined. Three types of vascular abnormality were seen: macrocirculation hemorrhages, microcirculation hemorrhages, and vascular stasis. As the supratentorial mass expanded and the intracranial pressure rose, there was a progression of vascular lesions from stasis to microcirculation hemorrhages, and finally to macrocirculation hemorrhages. The microcirculation hemorrhages occurred in stuporous animals, and the macrocirculation hemorrhages in comatose animals. Microcirculation hemorrhages were distributed primarily in the tectum, and macrocirculation hemorrhages were mainly in the tegmentum. Microcirculation hemorrhages first appeared in association with moderate to severe intracranial hypertension; macrocirculation hemorrhages were seen mainly with extreme intracranial hypertension. The clinical implications of these brain-stem vascular lesions are discussed.

The Brain

A fatal impaling-type head injury is described in a young man, sustained when he crashed his car while intoxicated, his head being transfixed by a broken wooden fence post. This shattered the facial bones and damaged the brain stem. Other published instances of impaling head injuries are discussed.

✓ The authors report the total surgical removal of five vascular lesions of the brain stem, three hemangioblastomas and two arteriovenous malformations. One patient died; among the others, the quality of survival is excellent. Factors favoring surgical removal of such lesions are discussed.
