Hepatic cyst associated with ventriculoperitoneal shunt in a child with brain tumor
Insights
A ventriculoperitoneal shunt complication caused liver dysfunction in a child. Repositioning the shunt resolved the liver cyst and symptoms, highlighting a rare but treatable condition.
Area of Science:
- Pediatric Neurosurgery
- Hepatology
- Medical Device Complications
Background:
- A 12-year-old boy with a thalamic grade IV astrocytoma required a ventriculoperitoneal (VP) shunt for cerebrospinal fluid management.
- VP shunts are common in pediatric neurosurgery but can be associated with various complications.
Observation:
- The patient presented with epigastric pain and signs of increased intracranial pressure.
- Laboratory tests revealed markedly elevated SGOT and alkaline phosphatase levels.
- Radiological imaging identified a cyst in the right lobe of the liver, extending to the porta hepatis.
Findings:
- A simple repositioning of the VP shunt led to the complete resolution of the patient's clinical symptoms.
- The liver cyst disappeared following the shunt adjustment.
- This case represents the first reported instance of a VP shunt-associated cyst involving the liver and causing hepatic dysfunction.
Implications:
- This case highlights a rare complication of ventriculoperitoneal shunts, emphasizing the need for considering shunt malfunction in patients with unexplained hepatic dysfunction.
- Early recognition and intervention, such as shunt repositioning, can effectively manage this condition.
- Further investigation into the mechanisms of VP shunt-related hepatic pseudocysts may be warranted.
Abstract:
A 12-year-old boy with a thalamic grade IV astrocytoma and ventriculoperitoneal (VP) shunt developed epigastric pain and symptoms of increased intracranial pressure. The SGOT and alkaline phosphatase levels were markedly elevated and the radiological studies showed a cyst in the right lobe of the liver, extending to the porta hepatis. Simple repositioning of the shunt resulted in complete resolution of clinical findings and disappearance of the cyst. Although abdominal pseudocysts associated with VP shunts have been reported, this is the first report of a cyst involving liver and causing hepatic dysfunction.
