Introduction:
We report a bizarre presentation of a distal shunt malfunction in a 5-year-old child with a ventriculoperitoneal shunt.
Discussion:
The plain radiographs done as a workup for possible shunt malfunction demonstrated the distal shunt tip reentering the abdominal wall from inside the peritoneal cavity. We discuss the possible explanation for the phenomenon.
Conclusion:
We conclude that the case is just another reminder of the fact that shunt malfunctions can have multiple presentations; hence, a regular follow-up with appropriate imaging and high index of suspicion is mandatory in preventing morbidities.
