Multiple cavernous malformations with supravermian arachnoid cyst

Cerebral cavernous malformation are congenital vascular abnormalities that have been reported in 0.4% of the population; they represent 5-13% of all cerebrovascular malformations. Onset of cerebral cavernous malformations may be associated with seizures, intracranial hemorrhages, focal neurological deficit or migraine-type headaches. Some patients may require surgical intervention due to hemorrhage. Multiple cavernomas in childhood have been reported in the literature, but they are rare. This manuscript presents a 12-year-old girl with multiple cavernomas accompanied by supravermian arachnoid cyst detected by neuroimaging techniques. This is the first report that demonstrates a case of pediatric multiple cavernous malformation coexisting with arachnoid cyst of the supravermian cistern.
