Intraventricular fetus-in-fetu. Case report
Insights
A rare case of a 14-cm intraventricular fetus was surgically removed from a 6-week-old infant. The infant experienced excellent recovery, highlighting successful surgical intervention for this congenital anomaly.
Area of Science:
- Developmental Biology
- Pediatric Neurosurgery
- Medical Imaging
Background:
- Congenital anomalies can present with complex mass effects within the central nervous system.
- Intraventricular fetal-in-fetu is an extremely rare congenital malformation.
Observation:
- A 6-week-old infant presented with rapidly enlarging head size due to an intraventricular mass.
- A 14-cm fetus, complete with recognizable limbs, trunk, head, and exomphalos, was identified within the lateral and third ventricles.
- The intracranial fetus was surgically removed in its entirety.
Findings:
- Histological and cytogenetical studies of the removed fetus were performed.
- The surgical procedure resulted in excellent recovery for the infant.
- The patient is now 18 months old and recovering well.
Implications:
- This case highlights the feasibility of complete surgical resection for large intraventricular fetal-in-fetu.
- Understanding the embryology and pathology is crucial for diagnosis and management.
- Successful outcomes emphasize the importance of early diagnosis and intervention in pediatric neurosurgery.
Abstract:
The authors present a case of an intraventricular 14-cm fetus in a 6-week-old infant who presented with enlarging head size. The entire intracranial fetus, with recognizable limbs, trunk, head, and exomphalos, was removed totally from the lateral and third ventricles, with excellent recovery in the patient, who is now 18 months old. The cytogenetical and tissue histological studies are reported. The embryology, operative procedure, and pathology of this condition are discussed and the literature briefly reviewed.
