Prenatal and postnatal MRI imaging findings of intracranial parasitic fetus: a case report


Fetus in fetu (FIF) is an extremely rare anomaly. It is predominantly seen retroperitoneally in 80% of cases but can present at atypical sites like the skull, sacrum, scrotum and the mouth. We reported a rare case of intracranial parasitic fetus. We described the prenatal and postnatal MRI findings of the case. There was no obvious spinal signal on the imaging findings at 35 weeks of gestation. However, the postnatal MRI revealed spinal column signal at 5 months and 11 days.
