Isolated Wormian Bone Detected during Second Trimester Scan by Means of 3D Sonography: Counseling and Management

Wormian bones are accessory bones that occur within the cranial suture and fontanelles, most commonly within the posterior sutures. The incidental 3D sonographic detection of isolated wormian bone during a second trimester sonographic examination is reported, together with the counseling and clinical management strategies that followed. We have demonstrated that supernumerary bone can be seen as an isolated sonographic finding in a healthy fetus or can be associated with multiple congenital anomalies. The sonographic detection of a fetus with wormian bone indicates the need for a very thorough examination and genetic counseling for the parents regarding prognosis and risk of recurrence.
