Abstract
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.

Core tip: We present two rare cases of multifocal intraventricular and/or paraventricular giant cavernous malformation (GCM) in small children including a literature review focused on location and imaging findings. The GCM is a rare entity. Intraventricular cavernous malformations are very rare and account for 2.5% of all brain cavernous malformations and are mostly found in the third ventricle. Characteristic magnetic resonance imaging findings such as multicystic lesions and a hemosiderin ring or bubbles-of-blood appearance can assist to differentiate GCMs from other intraventricular tumors/masses.
