Oligodendrogliomas rarely grow primarily in the ventricles. When compared to more common hemispheric counterparts, such intraventricular oligodendrogliomas, or oligodendrogliomas of the midline group (Martin), present distinct clinical features, namely, (1) they occur in the younger age, (2) an interval between clinical onset and diagnosis or operation is shorter, and (3) initial symptoms are most often limited to those of increased intracranial pressure, although the patient may occasionally present mild organic dementia, callosal disconnection syndrome, and/or mild gait ataxia. Two cases of oligodendroglioma primarily involving the lateral ventricle are reported in female patients, aged 29 and 19, respectively, with sole complaints of an increased intracranial pressure. Magnetic resonance imaging proved to be most useful as a radiologic diagnostic procedure. The tumor was radically removed via a para-falcine transcallosal approach without causing any persistent neurological deficits. Merit and demerit of the approach are briefly discussed.
少突胶质细胞瘤很少主要起源于脑室。与更常见的半球型少突胶质细胞瘤相比，这种脑室内少突胶质细胞瘤或中线组少突胶质细胞瘤（马丁分类）具有明显的临床特征，即：（1）发病年龄较轻；（2）临床发病与诊断或手术之间的间隔较短；（3）初始症状最常仅限于颅内压升高的症状，尽管患者偶尔可能出现轻度器质性痴呆、胼胝体离断综合征和/或轻度步态共济失调。本文报告了2例主要累及侧脑室的少突胶质细胞瘤病例，患者均为女性，年龄分别为29岁和19岁，唯一的主诉是颅内压升高。磁共振成像被证明是最有用的放射学诊断方法。通过经胼胝体旁矢状窦入路将肿瘤彻底切除，未导致任何持续性神经功能缺损。本文简要讨论了该入路的优缺点。
