The authors have collected eighteen cases of primary intraventricular lesions revealed by a subarachnoid haemorrhage. Among these cases, the most important are the choroid plexus papillomas followed by ependymomas; some cases have no precise histological interpretation. Generally speaking, cerebral arteriography gives only indirect evidence of ventricular dilation and thus does not confirm the presence of a lesion. On the contrary, the pneumoencephalogram is consistantly positive, but does not give the differential diagnosis between intraventricular tumours and primary intraventricular haemorrhages. This test should therefore be given the same importance as spinal cord arteriography in the exploration of subarachnoid haemorrhages with negative cerebral angiograms.
作者收集了18例由蛛网膜下腔出血发现的原发性脑室内病变病例。在这些病例中，最重要的是脉络丛乳头状瘤，其次是室管膜瘤；有些病例没有确切的组织学诊断。一般来说，脑血管造影仅能间接显示脑室扩张，因此不能确诊病变的存在。相反，气脑造影结果始终为阳性，但不能对脑室内肿瘤和原发性脑室内出血进行鉴别诊断。因此，在脑血管造影阴性的蛛网膜下腔出血检查中，该检查应与脊髓血管造影给予同等重视。
