摘　　要：患者女性,33岁。因右眼眶周红肿、疼痛12 h就诊眼科。CT表现为右侧视神经增粗、肿大;头颅MRI可见胝体压部、双侧海马、丘脑、基底节、颞顶叶及左侧额叶异常信号;眼部B超可见右侧玻璃体腔高回声信号、视盘隆起。患者2年前有左侧枕叶胶质瘤手术、放疗、化疗病史,病理结果提示星形胶质细胞瘤(世界卫生组织分级Ⅱ级)。结合病史,确诊为左侧枕叶星形胶质细胞瘤右侧海绵窦侵犯,左侧枕叶星形胶质细胞瘤双侧视路侵犯,右侧玻璃体腔星形胶质细胞瘤种植。A 33-year-old female presented to the ophthalmology clinic with right periorbital redness and pain for 12 hours.CT revealed right optic nerve thickening and enlargement.Cranial MRI demonstrated abnormalities in the corpus callosum,bilateral hippocampi,thalamus,basal ganglia,temporal-parietal lobes,and the left frontal lobe.Ocular B-scan ultrasound showed elevated optic disc and high echogenic signals in the right vitreous cavity.The patient had a history of surgical resection,radiation therapy,and chemotherapy for a left occipital glioma two years prior,with pathology indicating astrocytoma(World Health Organization Grade Ⅱ).Combining the patient′s history and diagnostic findings,the confirmed diagnosis is bilateral occipital astrocytoma with invasion into the right transverse sinus,bilateral optic pathways involvement related to the left occipital astrocytoma,and seeding of astrocytoma in the right vitreous cavity.
