Giant intraventricular and paraventricular cavernous malformations with multifocal subependymal cavernous malformations in pediatric patients: Two case reports

Figure 1 Pre-operative brain computed tomography and magnetic resonance imaging. A: Non-contrast computed tomography shows cystic-solid mass (white arrows) with internal calcifications (black arrows) in body of left lateral ventricle and intraventricular hemorrhage (arrowheads) resulting in hydrocephalus; B: Axial T1 weighted image; C: Axial T2 weighted image; D: Sagittal T2 weighted image; E: Axial T2* weighted mage; F: Axial T1 weighted post gadolinium administration image show a solid-cystic intraventricular mass (arrows) at the left trigone and body of left lateral ventricle with internal calcification, perilesional brain edema and various stages of hemorrhage; bubbles of blood appearance. Another small slightly enhanced nodule (arrowhead) at the subependymal region of the posterior body of the left lateral ventricle is seen.
