Summary
We have studied 15 cases of spontaneous intracerebellar haematomas in 9 males and 6 females. A significant correlation between the clinical presentation and the CT scan features of benign and fatal haemorrhages of the cerebellum is presented.
Diagnostic computerized tomographic studies were performed in a mean interval of 31 hours after the initial symptoms. 60% were diagnosed and treated in less than 24 hours; 11 patients had haematomas larger than 3 cm, and 5 (45%) of these cases died with evidence of irreversible brain-stem damage. Twelve (80%) showed compression of the fourth ventricle, 9 (60%) obliteration of the brainstem cisterns and 8 (53%) ventricular dilatation.
8 cases were treated with surgery; 50% of them showed neurological improvement, including two cases with signs of brain-stem compression. 7 patients who were treated conservatively were followed closely with repeated CT scans, which showed that resolution of the mass effect and isodensity of the haematomas occurred within 9 to 15 days, with a mean of 11 days, after the initial CT scan. An increased mortality was observed with haematomas larger than 3cm (73%), hydrocephalus (45%) and intraventricular haemorrhage (40%). Smaller haematomas without CT scan evidence of obliteration of the brain-stem cisterns or hydrocephalus had a better outcome.
