Tobi and Gayathri
What is it ? Fetus in fetu is a developmental abnormality in which a mass of tissue resembling a fetus forms inside the body. fetus-in-fetu is a developmental abnormality where, in utero, the larger of a set of twin fetuses absorbs the other into their body. The condition is usually diagnosed shortly after the surviving twin is born although in a few horrific cases, the absorbed twin is not discovered until adulthood or death.
Causes ? 1.Teratoma theory Fetus in fetu may be a very highly differentiated form of dermoid cyst 2. Parasitic twin theory Fetus in fetu may be a parasitic twin fetus growing within his or her host twin. Very early in a monozygotic twin pregnancy, in which both fetuses share a common placenta, one fetus wraps around and envelops the other. The enveloped twin becomes a parasite, in that his or her survival depends on the survival of his or her host twin, by drawing on the host twin's blood supply.
Symptoms Most of the cases present during infancy, but late presentation has also been reported. The major presenting complaint is a palpable abdominal mass, predominantly in upper abdomen. The other symptoms are secondary to the mass effect of the FIF such as: jaundice hydronephrosis intestinal obstruction meconium peritonitis respiratory distress vomiting
Treatment The surgical removal of the twin fetus is the treatment of choice It will relieve obstruction, prevent further compression and possible complications. Complete excision allows confirmation of the diagnosis and lowers the risk of recurrence
Diagnosis Most of the cases present during infancy, but late presentation has also been reported. It is diagnosed through: Ultrasound X-ray CT scan
Statistics Most cases of fetus in fetu are caught when the host twin is an infant Fewer than 100 examples have been documented Doctors estimate that it happens at 1 in every 500,000 births. The scenario does happen in equal rates to males and females. When they are removed, the fetus are about 1.5 to 9.5 inches (4 to 24.5 centimeters) in length and weigh between 0.04 ounces (1.2 grams) and 4 pounds (1.8 kilograms ).
Case study 1 sanjay bhagat One night in 1999, 36-year-old Sanjay was rushed to the hospital. Initially doctors thought there was a tumor in his stomach. The tumor was so large that it pressed the diaphragm. As Doctor Ajay Mehta push into Sanju’s stomach, he felt there were a lot of bones in it, then one by one, parts of the body exit: genitals, hair, jaw, arms, legs. At first glance, it looks like Sanju Bhagat pregnant child. However, in truth he had twin fetuses 'trapped' in the body, as a parasite, for 36 years!
