MRI capture of intermittent ventriculomegaly in a patient with ventriculo-peritoneal shunt

Area of Science:

• Neuro-oncology
• Neurosurgery
• Pediatric Neurology

Background:

• Ventriculo-peritoneal shunts are common in managing hydrocephalus secondary to pediatric brain tumors.
• Intermittent changes in ventricular size are a known, yet infrequently documented, complication of these shunts.

Observation:

• A 3-year-old boy with medulloblastoma presented with intermittent ventriculomegaly.
• This phenomenon was identified during a single magnetic resonance imaging (MRI) session.

Findings:

• The case provides definitive imaging evidence of intermittent ventriculomegaly in a patient with a ventriculo-peritoneal shunt.
• This finding is rare and challenges typical imaging interpretations of shunt function.

Implications:

• Highlights the importance of considering intermittent shunt malfunction in pediatric hydrocephalus management.
• Suggests that advanced imaging techniques may be crucial for diagnosing subtle shunt complications.
• Informs neurosurgical and neurological management strategies for pediatric patients with shunts and brain tumors.
