Die pränatale Diagnose eines Hygroma cysticum colli congenitum. Ein Vergleich sonographischer und computertomographischer Befunde

Abstract

In a case of prenatal diagnosis of lymphangioma (hygroma) of the neck the results of sonographic and computer tomographic investigations were compared. It was shown that the methods are complimentary and lead to very similar conclusions. The first investigation should be by ultra-sound because of the lack of radiation. The computer tomography is then indicated with specific questions in mind and the radiation exposure can be minimized. In the presented case the combination of sonography and computer tomography permitted a prognosis of poor operability of the lesion. Since the prognosis cannot be determined with complete certainty prior to delivery the obstetrician and neonatalogist need to proceed with the possibility of a treatable anomaly in mind. The neckopsy findings in our case confirmed the inoperability of the lesion.
