脑瘤所引起的颅内出血可掩盖其原病因,混淆诊断,影响治疗和预后。作者报告8例的经验。80例病因已证实的自发性脑内血肿中,8例(10%)系由原发或转移性新生物所引起。如将6例转移瘤除外,则发病率为2.5%。血肿体积均较大,直径超过4厘米。病人的症状和体征表现为两种类型。第一类(3例)为典型的自发性脑内出血:有高血压病史,突然头痛,昏迷或木僵,轻瘫或偏瘫以及血性脑脊液。第二类(5例)为具有颅压增高的症状与体征并有限局性神经体征。4例作了脑血管造影,其中3例显示为不明原因的占位性病变。两例作了同位素脑扫描,均提示为肿瘤。通过血块、可疑的肿瘤组织或腔壁活检作出诊断。两例术后死亡;其余6例于 Intracranial hemorrhage caused by brain tumors can mask its original etiology, confuse diagnosis, affect treatment and prognosis. The author reported 8 cases of experience. Eighty cases (10%) of the 80 cases of spontaneous intracerebral hematoporosis proved to be caused by primary or metastatic neoplasms. Except for 6 metastases, the incidence was 2.5%. Hematoma volume is larger, more than 4 cm in diameter. There are two types of patients’ symptoms and signs. The first type (3 cases) is a typical spontaneous intracerebral hemorrhage: history of hypertension, sudden headache, coma or stupor, light sputum or hemiplegia, and bloody cerebrospinal fluid. The second category (5 cases) had symptoms and signs of increased intracranial pressure and limited local neurological signs. Cerebrovascular angiography was performed in 4 cases, of which 3 cases showed occult lesions. Isotopic brain scans were performed in both cases, all suggesting a tumor. Diagnosis is made by blood clots, suspicious tumor tissue, or a cavity wall biopsy. Two patients died after surgery; the remaining 6 patients
