Congenital granular cell tumor (epulis): postnatal imaging appearances.
A newborn girl with histologically confirmed epulis presented with a 2.6-cm mass protruding from her mouth. An ultrasound study performed in antenatal week 25 was unremarkable. Postnatal ultrasound showed a mass, hyperechoic centrally, hypoechoic peripherally, containing crowded branching vessels. MRI revealed a nonenhancing gingival mass exhibiting an isointense rim on T1-weighted imaging and a low-intensity rim on T2-weighted sequences. MRI better defined its gingival origin and lack of local extension. A gingival solid mass in a newborn with branching vessels and a peripheral rim on imaging may suggest congenital epulis.
