Le diagnostic échographique d’une tumeur fœtale dépend de l’âge gestationnel et de la position fœtale, de la localisation et de la taille tumorale, ainsi que la formation de l’opérateur. Nous rapportons le cas d’un hémangiome volumineux du membre inférieur gauche. La prise en charge et le diagnostic rapides sont de bon pronostic. Une exérèse chirurgicale rapide et son bien-fondé sont discutés.

An echogenic tumor (22×22mm) isolated from the anterior part of the left leg at 27 WA of pregnancy suggested an angiomatous structure. This mass appeared to be well vascularized on Doppler examination. Three-dimensional imaging showed connections with adjacent tissues. The limbs were mobile. Delivery of a 3990-g-boy occurred normally. On the anterior part of the left leg, there was a plate-shaped mass with a pink hole at the superior part. Excision under general anesthesia was performed at the first month because of the risk of rupture and bleeding. The dissection was easy with the deep plane. Healing was complete 10 days after the surgical procedure and the aesthetic aspect was good 1 year later. Histological findings of the suspect mass emphasize the vascular aspect of the tumor. A hemangioma capillary with venous structures in the dermal hypodermic area was found.
