Transient ventriculoperitoneal shunt malfunction in a pediatric patient: An illustrative case.

Background: Ventriculoperitoneal shunt (VPS), the mainstay of the treatment for hydrocephalus, is associated with relatively high revision rates. Transient hydrocephalus due to intermittent VPS obstruction should be recognized as a cause of VPS malfunction. While transient VPS dysfunction is well-recognized complication, there is a relative paucity of well-documented cases in the literature.

Case Description: We present the case of a 4-year-old boy with a history of vascular malformation and hydrocephalus secondary to intraventricular hemorrhage. The patient presented with transient, self-resolving hydrocephalus (without intervention), as documented by clinical and radiological findings.

Conclusion: Transient hydrocephalus due to intermittent VPS dysfunction in children is a rare entity, but it should be suspected in certain patients with VPS presenting with transient or self-improving symptoms.
