Case histories are reported of seven patients in whom the diagnosis of cerebellar (four) or pontine hemorrhage (three) was made by computerized axial tomography (CT). In all of the patients except two the diagnosis, established on the basis of a space-occupying high absorption lesion, was proved by either operation or autopical for an intracerebral hematoma, i.e., the high absorption zone was transformed into an area of reduced density. It is concluded that CT is a highly reliable method for the diagnosis and location of posterior fossa hematomas. A CT syndrome, observed in four of the seven cases, is described consisting of a hydrocephalus with the tips of the posterior horns being filled with blood. This seems to be specific for a posterior fossa hematoma having penetrated into the fourth ventricle.

Transluminal angioplasty of stenotic carotid arteries: case reports and protocol.

Transluminal angioplasty of the carotid artery was successfully performed without complications in two patients, one with a stenotic internal carotid artery and one with a stenotic common carotid artery. Effectiveness of the procedure was proven by amelioration of common carotid flow. The authors outline factors to be considered in selecting patients for this procedure, including the particular cerebrovascular pathogenesis, type of stenotic lesion, clinical indications, and technique and materials used for dilatation.
