Aneurysm of the interatrial septum is a potential cause of systemic embolism, but it is rarely responsible for a cerebral embolism in childhood.
A girl, aged 14 years, presented with a sudden right hemiplegia. The coagulation factors were normal, as was the CSF. The CT scan was normal and the EEG showed some theta waves (3-4/s) on the left temporal lobe. MRI, performed 6 days later, showed ischemic lesions leading to a search for the origin of the embolism. One-dimensional echocardiography revealed no abnormality, but two-dimensional echocardiography showed an aneurysm of the interatrial septum bulging into the right atrium. The child was treated with low doses of acetylsalicylic acid, but still had a moderate degree of spastic hemiplegia one year later.
Cardiopathies can be among the causes of cerebral embolism in children. An aneurysm of the interatrial septum requires treatment throughout patient's life.
房间隔瘤是系统性栓塞的一个潜在原因，但在儿童期很少导致脑栓塞。
一名14岁女孩，突发右侧偏瘫。凝血因子正常，脑脊液也正常。CT扫描正常，脑电图显示左颞叶有一些θ波（3 - 4次/秒）。6天后进行的MRI显示有缺血性病变，从而对栓塞的起源进行了查找。一维超声心动图未显示异常，但二维超声心动图显示有一个房间隔瘤突入右心房。该患儿接受了小剂量阿司匹林治疗，但一年后仍有中度痉挛性偏瘫。
心脏病可能是儿童脑栓塞的病因之一。房间隔瘤需要终生治疗。
