Figure 1. Gray-scale (A) and color Doppler (B) ultrasound images of the case at 38 weeks revealed a 32×22 mm right frontal heterogeneous mass with various focal hypoechogenic (red arrow). A few small hyperechogenic foci can be observed in the lesion and a wide base of case can be detected close to frontal bone. (C) Axial T2-weighted image of case at 38 weeks on MRI. The mass appears hyperintense of the mass in the frontal bone (red arrow). (D) Axial T2-weighted image of case on MRI revealed 1 day later after birth (red arrow). (E) Ultrasound revealed right-sided temporal heterogeneous and fusiform mass in the frontal bone 1 day after birth. (F) The tumor was complete involution in the T1-weighted image 1 year later.
