作者报告自1942年10月到1974年4月所收集的经组织学证实的90例枕叶占位性病变。仅局限于枕叶者36例,并侵犯邻近脑叶者54例。(枕叶白质病变57例,皮质者33例)。其性质为:原发性58例(恶性胶质细胞瘤26例,“良性”胶质细胞瘤11例,脑膜瘤19例,肉瘤1例,血管母细胞瘤1例),继发性32例(转移瘤16例,脓肿15例,包囊虫囊肿1例)。临床表现起病方式:逐渐起病的53例(58.9%):其表现为颅内压增高者46例(59%),头痛者63例(70%)。作者认为此等比例之所以较高,系因占位性病变压迫窦汇区,颅内静脉回流受阻导致早期脑水肿之故。急性起病的37例(41%),其中表现为视幻觉或视错觉的11例,非视觉性癫痫发作的10例。
The authors reported on histologically confirmed 90 cases of occipital occupying lesions collected from October 1942 to April 1974. Confined only to the occipital lobe in 36 cases and invaded the adjacent lobe in 54 cases. (57 cases of occipital white matter lesions and 33 cases of cortex). Its nature is: Primary 58 cases (26 cases of malignant glioblastoma, 11 cases of “benign” glioblastoma, 19 cases of meningioma, 1 case of sarcoma, 1 case of hemangioblastoma), secondary to 32 cases (16 metastases, 15 abscesses, 1 cyst of cysts). Clinical manifestations: 53 cases (58.9%) with progressive onset: 46 cases (59%) with increased intracranial pressure and 63 cases (70%) with headache. The authors believe that the high proportion of these ratios is due to space-occupying lesions oppressing the sinus commissure region, and hindrance of intracranial venous return due to early brain edema. There were 37 cases (41%) of acute onset, including 11 cases of visual hallucinations or visual illusions and 10 cases of non-visual seizures.
