EP06.78: Facial fetal hemangioma

A 35-year-old patient presented to our hospital at 17 weeks' gestation for her first pregnancy with a low-risk combined first trimester screening. US performed at 21w was normal. A routine ultrasound scan at 28.6 weeks detected a facial mass with no other abnormalities. The mass was located on the right side of the face, between the infraorbital rim and the mandible, and appeared hypogenic, homogeneous, with well-defined borders, measuring 35x25mm. Colour Doppler study suggested increased vascularisation. The mass did not extend into the orbit and the bone structures were preserved. A diagnosis of facial hemangioma was suspected and echocardiography was performed to assess fetal cardiac function. At 30 weeks' gestation, MRI was performed and confirmed the US findings: a well-defined solid mass in the right malar region within the subcutaneous soft tissues, measuring 42x22x28mm. Slightly hyperintense on T2, with tubular images within; the lesion was bordered by fatty planes in its posterior border, with no evidence of intraorbital extension, intranasal or within the masticatory space. The external Jugular vein, the common Carotid artery, and the right external Carotid artery were prominent. Subsequent ultrasound scans showed an increase in the mass volume until it measured 47x20x34mm at 36 weeks' gestation. An elective Caesarean section was performed at 37.4 weeks to avoid fetal trauma during delivery and a healthy 2800g male was born with a normal Apgar score. Neonatal examination revealed a well-defined bluish-purple 50x35mm mass on the right side between the infraorbital rim and the mandible, covered by skin. There was no evidence of heart failure or other associated abnormalities. Final diagnosis was Rapidly Involutive Congenital Hemangioma (RICH) and the patient required only dermatological follow-up with spontaneous regression of the mass during his first year of life.
