Prenatal sonographic diagnosis of a congenital oral fibrovascular hamartoma

We report the diagnosis of a congenital oral fibrovascular hamartoma with 2D 3D ultrasound. The distinctive sonographic features including the fibrovascular stalk and a single vascular pedicle are described. Prenatal MR and postnatal CT confirmed the ultrasound appearances. Despite concerns about impaired swallowing, the prenatal and perinatal course was straightforward. The lesion was removed soon after birth. Histopathology of the removed lesion provided the definitive diagnosis of a fibrovascular hamartoma and reported a cellular composition which differentiates it from similar lesions. To our knowledge, such a lesio n has not been reported pre or postnatally and provides an alternative differential diagnosis for a fetus presenting with a mouth mass.
