[Cervical congenital hemangioma: diagnosis and management difficulties]. / Hémangiome cervical congénital: difficultés de diagnostic et de prise en charge.

Rapidly involuting congenital haemangioma (RICH) is a rare vascular tumour whose antenatal diagnosis is difficult. During ultrasound examination at 32nd weeks' gestation, a voluminous heterogeneous cephalic lesion was discovered that could be a haemangioma or a teratoma. A caesarean delivery was performed. The tumour was removed directly after birth. The pathology examination concluded on a RICH. Antenatal, prepartum and postnatal management are not consensual and must consider the lesion size.

Quantification of intrathoracic liver herniation by magnetic resonance imaging and prediction of postnatal survival in fetuses with congenital diaphragmatic hernia.

OBJECTIVE: To quantify the degree of intrathoracic liver herniation by magnetic resonance imaging (MRI) and evaluate its effect on postnatal survival in fetuses with isolated congenital diaphragmatic hernia (CDH). METHODS: Forty fetuses that were expectantly managed and that were delivered after 32 weeks' gestation were included in this study. On axial T2 weighted MR images the degree of intrathoracic liver herniation was measured by volumetry, using the xyphoid process and thoracic apex as landmarks. The ratio of the volume of the liver that was herniated into the thoracic cavity to the volume of the thoracic cavity was calculated (LiTR). All the fetuses also underwent lung volumetry, and the ratio of the observed/expected total fetal lung volume (o/e TFLV) was calculated. Regression analysis was used to investigate the effect on survival of side of occurrence of CDH, o/e TFLV, LiTR and gestational age at delivery. Receiver-operating characteristics (ROC) curves were constructed to examine the prediction of survival by o/e TFLV or LiTR alone and o/e TFLV and LiTR together. RESULTS: Univariate regression analysis demonstrated that significant predictors of survival were o/e TFLV and LiTR. Multiple regression analysis demonstrated that o/e TFLV and LiTR provided independent prediction of survival. The area under the ROC curve (AUC) for the prediction of postnatal survival from o/e TFLV alone was 0.846 (P < 0.001; SE = 0.062) and the AUC from LiTR alone was 0.875 (P = 0.001; SE = 0.072). The AUC for the prediction of postnatal survival from o/e TFLV and LiTR combined was 0.912 (P < 0.001; SE = 0.045), however it was not statistically significantly different from that of o/e TFLV alone. CONCLUSION: In expectantly managed CDH fetuses, assessment of LiTR using MRI provided prediction of postnatal survival independently from o/e TFLV.
