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.
