title: An anatomical fetal brain structure and a normal variant mimicking anomalies on routine neurosonographic imaging: report of two cases.
abstract: We present two cases in which an anatomical structure, the calcar avis, and a normal variant, a bifid choroid plexus, mimicked abnormalities on routine prenatal ultrasound examination. To the best of our knowledge these pitfalls have only been described in neonates. A familiarity with these false images is important to avoid erroneous diagnoses.
