 Unilateral asymmetric enlargement of the atrium of the right lateral ventricle is seen likely representing an intraventricular cystic lesion measuring 16 x 12 mm in the axial plane. There are no findings to suggest acute or chronic blood product within this lesion. No brain parenchymal abnormalities are identified otherwise. There is no significant mass effect or midline shift. The remainder of the ventricular system is normal in size and morphology.
Findings suggesting the presence of a choroid plexus cyst within the right ventricular atrium without evidence of hemorrhage.This exam was discussed with Dr. Sarosh Rana from Obstetrics/Maternal Fetal Medicine at 3:10 p.m. today.
