抄録

We present 2 cases of arteriovenous malformation (AVM) in children that recurred 5 and 16 years, respectively, after initial total extirpation confirmed by cerebral angiography. In the first case, a parasplenial AVM that presented initially as a hemorrhage in a 5-year-old patient was completely resolved. Sixteen years later, it reappeared posterior to its initial location in the nidus and then ruptured. The second case also presented initially with AVM-related hemorrhage. Five years following extirpation of the diffuse paracallosal AVM in the right frontal lobe, the defect reappeared surrounding the location of the initial lesion and continued to grow.<br> These cases demonstrate that even in cases where cerebral angiography and operative findings confirm total extirpation of an AVM, the AVM may recur after 10 years or longer. Thus, long-term follow-up is recommended in such cases, especially for children.<br>
