By its ability to differentiate the densities of various intracranial tissues, computed tomography is an ideal tool to investigate the postoperative course and complications of neurosurgical patients. The most important immediate postoperative complications are intracerebral edema and epidural, subdural or intracerebral hematomas. The extent of surgical resection of neoplasms can also be studied easily by CT. The method of investigation and representative cases are described.

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 autopsy. In the two remaining cases, the evolution on CT was typical 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.
