Intracranial fetus-in-fetu

Article Abstract:

Ultrasound examination may detect the presence of a fetus-in-fetu pregnancy. Fetus-in-fetu is a very rare tumor caused by abnormal fetal development where parts of one fetus are found inside its twin. A 24-year-old woman underwent ultrasound examination at 24 weeks of pregnancy because she noticed decreased fetal movements for several days. Ultrasound revealed one fetus with a huge head containing abnormal structures. The fetus was delivered and an autopsy revealed a very large tumor inside the head that contained fetal limbs. Fetus-in-fetu may be difficult to distinguish from teratoma.
