脉络丛血栓形成伴出血甚少见,可由脑室造影损伤、继发性梗死、血栓形成、脉络丛动脉栓塞、血管瘤、动脉瘤、黄色肉芽肿及出血性出血素质所致。但我们尚未见到DIC导致脉络丛血栓形成及出血的报导。 Down氏综合征患者发生的脉络丛血栓形成,主要归因于这种遗传性疾病的血管缺陷,但我们的病例没有这种改变。 Choroidal plexus thrombosis with bleeding is rare, by intraventricular injury, secondary infarction, thrombosis, choroid plexus embolism, hemangioma, aneurysm, yellow granuloma and hemorrhagic diathesis due to quality. However, we have not yet seen reports of DIC causing choroid plexus thrombosis and bleeding. Choroid plexus thrombus formation in Down’s syndrome is mainly due to vascular defects of this hereditary disease, but not in our case.
