Complete involution of prenatally-diagnosed fetal scalp hemangioma.
OBJECTIVE
Scalp hemangioma is a rare benign fetal tumor. Here, we describe the detailed imaging features and natural course of a fetal scalp hemangioma until 1 year of age.


METHODS
We encountered a case of scalp hemangioma at 23 weeks' gestation by prenatal ultrasonography and magnetic resonance imaging. The mass persisted postnatally, but spontaneously regressed after birth.


CONCLUSIONS
Proper diagnosis with prenatal ultrasonography and magnetic resonance imaging is important when a scalp mass is suspected in utero. Continuation of the pregnancy after appropriate counseling is prudent, considering the favorable prognosis and the rate of spontaneous regression of uncomplicated cases.
