Summary
A child with tuberculous meningitis and hydrocephalus developed a rare subcutaneous fluid collection near a shunt tube. Drainage resolved the swelling and subdural effusion, suggesting a unique complication.
Area of Science:
- Pediatric Neurosurgery
- Infectious Diseases
- Neurology
Background:
- Hydrocephalus management often involves cerebrospinal fluid (CSF) shunting.
- Tuberculous meningitis (TBM) is a severe infection requiring prompt treatment.
- Ventricular shunts can be complicated by various issues, including infections and CSF collections.
Observation:
- A pediatric patient with hydrocephalus secondary to TBM presented with a subcutaneous fluid collection at the ventriculoperitoneal shunt entry site.
- Imaging revealed decompressed ventricles alongside bilateral frontoparietal subdural hygromas.
- The subcutaneous swelling correlated with the subdural fluid collections.
Findings:
- The subcutaneous fluid collection was identified as a unique complication associated with ventriculoperitoneal shunting in TBM.
- Bifrontal burr hole drainage successfully resolved both the subdural effusion and the subcutaneous scalp swelling.
- The pathogenesis of this specific complication was considered.
Implications:
- This case highlights a rare but treatable complication of CSF shunting in the context of tuberculous meningitis.
- Prompt recognition and appropriate surgical intervention (burr hole drainage) can lead to favorable outcomes.
- Further investigation into the pathogenesis of such shunt-related complications is warranted.
