Prenatal diagnosis of congenital soft tissue hemangioma of the fetal back

Abstract

Congenital hemangiomas are benign vascular lesions found in fetuses. Congenital hemangiomas develop in utero, have a maximum size at birth (in the absence of subsequent bleeding). Such hemangiomas occur in 1–2% of newborns. Prenatal ultrasound diagnostics and magnetic resonance imaging occupy an important place in the diagnosis, which determines the tactics of management and treatment of the patient. To present a clinical case of prenatal diagnosis of congenital soft tissue hemangioma of the fetal back. A pregnant woman A., 34, was sent to St. Petersburg State Public Health Institution «Diagnostic Center» (medical and genetic) with suspected spina bifida of the fetus after screening in late pregnancy period in one of the Birth Centres. Performed prenatal ultrasound (US) pregnant A. for a period of 34 weeks. According to ultrasound data in the region of the spine at the level of XI–XII thoracic vertebrae, an ovoid formation with clear even contours, a fairly homogeneous solid structure, with a clear capsule, 33×24×30 mm in size (volume 12.4 cm³) is determined subcutaneously. The diagnosis made: hemangioma of the soft tissues of the fetal back. Prenatal screening plays a key role in the diagnosis of congenital hemangiomas. Timely detection of this benign formation affects the tactics of management and delivery.
