Shamrock fetus in fetu: An anesthetic enigma

Abstract

Fetus in fetu (FIF) is a rare congenital anomaly with an incidence of 1 in 5 lakh live births. Till date, only 200 cases have been reported, with the majority having a single FIF. We report an interesting case of FIF with 3 interlinked fetuses inside giving the appearance of Shamrock leaf. The FIF was causing compression of the common bile duct causing obstructive jaundice as well as was associated with moderate hydronephrosis, presenting unique anesthetic challenges. Our purpose to write this case report was to add to the existing knowledge of this rare entity besides discussing its anesthetic implications.
