ObjectiveSpontaneous cerebellar hemorrhage (SCH) is less common than supratentorial intracerebral hemorrhage. This study investigated the treatment of SCH and the relation between its clinical and radiological manifestation and outcome.Materials and MethodsWe presented a SCH management protocol in our institute and analyzed the clinical and radiological findings in 41 SCH patients. The outcomes of each method (surgery and conservative treatment) were compared among patients with initial Glasgow Coma Scale (GCS) score of 9-13 and hematoma volume greater than 10 mL.ResultsTwo (4.9%), 16 (39%), and 23 (56.1%) patients had an initial GCS score of 3-8, with 3-8, 9-13, and 14-15, respectively. Initial GCS score showed significant correlation with Glasgow Outcome Scale (GOS) score (p = 0.005). The mean largest hematoma diameter was 3.2 ± 1.5 cm, and the mean volume was 11.0 ± 11.5 mL. Both of them showed significant inverse correlation with GOS score (p < 0.001). Among patients with an initial GCS score of 9-13 and hematoma volumes greater than 10 mL, 3 (50%) had good outcome and 3 (50%) had poor outcome in the surgical, and all of those in the conservative treatment group had poor outcomes. The outcome distribution differed significantly in the surgical and conservative groups (p = 0.030).ConclusionInitial GCS score and largest hematoma diameter and volume on brain computed tomography are important determinants of outcome in SCH patients. The surgery group showed better outcome than the conservative treatment group among those with an intermediate neurological status and large hematomas.
