摘　　要：BACKGROUND Giant cavernous malformation(GCM)is rarely found in intraventricular or paraventricular locations.CASE SUMMARY We present two cases of 6-mo and 21-mo boys with intraventricular and paraventricular GCMs including a literature review focused on location and imaging findings.Characteristic magnetic resonance imaging findings such as multicystic lesions and a hemosiderin ring or bubbles-of-blood appearance can assist in the differential diagnosis of a hemorrhagic intraventricular and/or paraventricular mass.CONCLUSION Multifocal intraventricular and/or paraventricular GCM in small children is rare.The characteristic magnetic resonance imaging findings can help to differentiate GCMs from other intraventricular tumors.BACKGROUND Giant cavernous malformation(GCM) is rarely found in intraventricular or paraventricular locations.CASE SUMMARY We present two cases of 6-mo and 21-mo boys with intraventricular and paraventricular GCMs including a literature review focused on location and imaging findings.
