Abstract: Objective: To investigate the etiology, clinical findings and treatment of spontaneous intracerebral hematoma （ICH）. Methods: 47 cases were reviwed. Results: All patients were examined by DSA, and we found 30 （63.8%） lesions, MRI showed 8 vascular abnomal in 13 patiens; The most common hemorrhagic factor is aneurysm （30.1%） while arteriovenous malformation （AVM） in the second （23.4%）, moyamoya disease（8.5%） and other disorders （17.0%） were less; The patients were classified into level 3 （Teases）, level 4 （13 cases）, and level 5 （27 cases） after the lesions were surgical operated on interventional neuroradiological treated. Conclusion: For all the spontaneous ICH patients, DSA examination is necessary.If the result is negative, they should be done MRI after hematomas disappear, aneurysm and AVM are common.In ICH.Most of the patients need etiological treatment including operation or embolization after emergent management for intracerebral hematoma or hydrocephalus.
