Fetal neck giant hemangioma associated with postnatal arising Kasabach-Merritt syndrome

Abstract

We report a prenatal ultrasound diagnosis of giant neck hemangioma at 30+1 weeks in a fetus resulting in the postnatal development of Kasabach-Merritt syndrome. Ultrasound scan revealed a large isoechoic mass occupying the whole neck, infiltrating the nasopharyngeal cavity, tongue, lower lip and mandible.

Complex sonographic visualization with 2D and 4D was helpful in the process of parental counseling.
