Abstract

A direct demonstration of intracerebral hemorrhage is not possible by conventional neuroradiologic methods. About 25% of temporal intracere-bral hematoma scan be diagnosed by echoencephalography in the hands of an expert. Angiography only permits detection of the signs of an intra-cranial space-occupying lesion. In direct signs of vessels close to the ventricle suggest in single cases the penetration of the hematomas in-to the ventricular system. The experience of neurosurgeons proved that an extended localization and possible ventricular penetration of spontaneous intracerebral hematomas was not assessed priortosurgery. Difficulties become even greater if bleeding occurs in the brain stem or posterior fossa. Diagnostic difficulties have been eliminated since the introduction of CT. Coagulated blood has a far higher radiation absorption than brain matter and it can be identified by EMI numbers between 29 and 37. Therefore a fresh coagulated intracerebral hematoma may easily be differentiated as a white, usually well-defined homogeneous zone with in the gray surroundings of brain matter. Large intra-cerebral hematomas with and with out ventricular penetration do not offer any diagnostic difficulties whatsoever. Small hematomas with a diameter of 2-3 mm in the basal ganglia and in the brain stem may also be detected with there solving power of the 160 x 160 matrix.
