Abstract
Fetus in fetus (FIF) represents an abnormal embryogenesis in monozygotic diamniotic twin gestation. It has been described in less than 200 cases worldwide. Differential diagnosis predominantly includes teratomas. The case presented here meets the accepted criteria of FIF and is one of the few prenatally diagnosed cases with FIF.
Zusammenfassung
In diesem Fallbericht werden die Kriterien einer Fetus-in-Fetu-Malformation erfüllt. Es ist einer der wenigen pränatal diagnostizieren Fälle und der einzige pränatale Fall mit extrafetalem Wachstum des parasitären Zwilling. Die wichtigste Differentialdiagnose eines Fetus in Fetu ist das Teratom. Die Therapie der Wahl ist die kompette Resektion, jedoch von dem Allgemeinzustand und zusätzlichen Fehlbildungen abhängig. Mit detaillierter Sonografie und moderner Bildgebung kann eine pränatale Diagnose gestellt werden und ermöglicht dadurch einen frühen und intedisziplinären Therapieansatz.
