Foetal vascular lesion-Case report

Frequency and preciseness of prenatal detection of foetal tumours increases due to improvement of sophisticated imaging methods. As correct diagnosis impacts the course of care in utero, it is essentially to improve diagnostic workout in a case of detected foetal anomalies. Here we report the case of partly involuting congenital haemangioma of foetus, which antenataly caused foetal secondary cardiomegaly. Pregnant woman was referred to Riga Maternity Hospital with unexplained tumour on the surface of foetal head at 24+2 weeks of gestation. Ultrasound exam revealed tubular structure without solid components between calvarium and skin under the left ear with very rich vascularization. Magnetic Resonance Image demonstrated enhancing multi-cystic lobulated mass. Hypertrophic secondary cardiomegaly was present without any additional structural abnormality. The foetus remained stable until 36+4 weeks of gestation, when the size of tumour succeeded 85 mm × 46 mm. Haemangioma was confirmed after delivery as round raised and infiltrating vascular lesion. After birth MRI demonstrated its connection with a. carotis externa. Propranolol was recommended with continuing follow-up. At 2 years and 3 months of age the lesion decreased by size noticeably, but still persists. Accurate diagnosis lets obstetricians to optimize antenatal care by providing an opportunity for planning deliveries, preparing family and medical staff for appropriate postpartum therapy and management.
