Summary
Fetus in Fetu (FIF) is a rare congenital anomaly where a parasitic twin develops within its host. This case highlights a retroperitoneal FIF diagnosed and resected in a 4-month-old fetus.
Area of Science:
- Developmental Biology
- Congenital Anomalies
- Pathology
Context:
- Fetus in Fetu (FIF) is an extremely rare congenital anomaly.
- Characterized by a vertebral axis within a mass, often with associated organs/limbs.
- Typically presents as a retroperitoneal mass, mimicking teratoma on imaging.
Purpose:
- To report a case of Fetus in Fetu (FIF) in a 4-month-old fetus.
- To describe the diagnostic and macroscopic/histological findings.
- To discuss the etiopathogenesis and differential diagnoses of FIF.
Summary:
- A 4-month-old fetus presented with a retroperitoneal mass diagnosed as Fetus in Fetu (FIF) via CT scan.
- Surgical resection revealed a fetiform mass with a vertebral axis, skin, and limb buds.
- Histology confirmed glial, skin, muscle, and bone tissues, solidifying the FIF diagnosis.
Impact:
- This case contributes to the understanding of FIF presentation and diagnosis.
- Highlights the importance of considering FIF in retroperitoneal masses.
- Reinforces the twin regression or defective implantation theories of FIF etiopathogenesis.

01:14Fetal Circulation
2.3K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

01:07Teratogenicity
3.9K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
