Case report

We present an unusual case of a fetus with an intracranial mass located in the lateral cerebral ventricle that was diagnosed by routine obstetric ultrasound at 37th week of pregnancy. Previous ultrasonographic observations were normal. A homogeneous solid mass occupied almost the whole space of the left lateral ventricle. Midline structures of the brain were displaced to the opposite side. The presumptive diagnoses were choroid plexus papilloma versus fetal intracranial hemorrhage. The newborn was delivered by a caesarean section at the 38th week of pregnancy. A neurosurgical operation with the extirpation of the tumor was performed 23 days after delivery. Histological evaluation confirmed the diagnosis of the choroid plexus papilloma. The infant is two years old now and is doing well.

Images 1, 2: 37 weeks of pregnancy; the image 1 shows a coronal gray scale view of the hyperechoic mass located within the left lateral cerebral ventricle representing the choroid plexus papilloma. The image 2 shows a parasagittal color Doppler scan of the left lateral cerebral ventricle showing the hyperechoic choroid plexus papilloma with a rich superficial vascularization.
