A case of meningioma following irradiation for a tumor of the third ventricle is reported. A four year old girl was admitted complaining of headache and vomiting. The pneumoventriculography revealed marked hydrocephalus and a mass lesion at the third ventricle. Under the diagnosis of a tumor of the third ventricle, ventriculo-atrial shunt and radiation therapy were performed. Totally, 4170 rad irradiation was directed from left temporal area through a single portal. Though she had no complaints for fourteen years, at the age of eighteen, she was admitted complaining of right hemiparasis and general convulsion. CT scan and left carotid angiogram revealed a left fronto-temporal tumor diagnosed as meningioma. Histological examination showed transitional type meningioma. The post-operative course was uneventful, and discharged without neurological sign except for slight right hemiparesis. A review of available literature revealed about 150 cases of post irradiated meningiomas. However, there were only 18 cases of meningiomas following irradiation for the treatment of brain tumors. These reported cases were also discussed.
报告了一例因第三脑室肿瘤接受放疗后发生的脑膜瘤病例。一名4岁女孩因头痛和呕吐入院。脑室造影显示明显的脑积水和第三脑室的占位性病变。在诊断为第三脑室肿瘤后，进行了脑室-心房分流术和放射治疗。总共通过单个照射野从左颞部区域进行了4170拉德的照射。尽管她在14年里没有任何不适，但在18岁时，她因右侧偏瘫和全身性惊厥入院。CT扫描和左颈动脉血管造影显示左额颞部肿瘤，诊断为脑膜瘤。组织学检查显示为过渡型脑膜瘤。术后过程顺利，除轻微右侧偏瘫外，无神经体征出院。对现有文献的回顾显示，约有150例放疗后发生的脑膜瘤病例。然而，因脑肿瘤治疗接受放疗后发生脑膜瘤的病例仅有18例。本文还对这些报道的病例进行了讨论。
