Spontaneous cerebellar hematomas (CH) represent 5%–10% of intracranial hemorrhages The purpose of this study was to describe CH characteristics in patients admitted to the critical care unit, to determine the prevalence of risk factors, to describe the clinical presentation, the treatment and the clinical situation at discharge. Thirty four consecutive patients were included. The mean age was 67±15 years. In the univariant analysis, only Glasgow Coma Score was associated with high mortality. An hematoma diameter > 3 cm., intraventricular hemorrhage and hydrocephalus were associated with mortality, but without statistical significance.
