[CT stereotactic biopsy in the differential diagnosis of deeply situated intracerebral hematomas].

The diagnosis of intracerebral haematomas, especially of those which are relatively small, occupy little space and are deeply situated, presents considerable problems. The problem is even greater when the expected acute case history and the acute beginning of the symptoms do not occur and unusual localisations are found. The consequences of this are false diagnoses and the treatment of these patients within the framework of blanket diagnosis "intracerebral tumours" or "space occupying processes" without any confirmation of the histological diagnosis. - Using a sample of 26 patients where the histological diagnosis of non-recent intracerebral hemorrhages had been confirmed (out of a series of 818 CT-stereotactically biopsied patients punctured by us from the beginning of 1983 until the end of 1984), the problem of establishing a diagnosis is exposed. - A histological diagnoses should in any case be confirmed before any thorough and deep-reaching therapy is begun, since false diagnoses and misinterpretations can cause serious consequences for the patient.
