著者用显微技术,经脑室通路成功地摘除了2例脑室内原发性少突胶质细胞瘤,并复习了有关文献。脑室内的少突胶质细胞瘤是非常罕见的。另外,据Reymond等(1950)报告,少突胶质细胞瘤亦可表现为继发性,是大脑内原发性肿瘤沿脑脊液通道播种而侵犯脑室的。病例报告: 例1:这个33岁男性,在1978年1月,诉说近来记忆力减退和额部头痛。在1978年3月因颅内压增高和突然意识丧失,双侧视乳头水肿和明显的四肢痉挛,被当作急症入神经外科治 By microscopy, the author successfully removed 2 cases of intraventricular primary oligodendroglioma via the ventricular access and reviewed the literature. Intraventricular oligodendrocytes are very rare. In addition, according to Reymond et al.’s (1950) report, oligodendroglial tumors can also manifest as secondary and invade the ventricles of the brain by sowing primary tumors along the cerebrospinal fluid channels. Case Report: Example 1: The 33-year-old man, in January 1978, complained of recent memory loss and headache. In March 1978 due to increased intracranial pressure and sudden loss of consciousness, bilateral papilledema and obvious limb spasm, was treated as an emergency neurosurgery
