Lateral ventricle plexus papilloma and communicating hydrocephalus

Area of Science:

• Pediatric Neurosurgery
• Neuro-oncology
• Cerebrospinal Fluid Dynamics

Background:

• Choroid plexus papillomas are rare tumors typically found in children.
• Hydrocephalus is a common complication, often requiring surgical intervention like shunting.
• Understanding the pathophysiology of hydrocephalus in this context is crucial for effective management.

Observation:

• A five-month-old boy presented with a choroid plexus papilloma in the right lateral ventricle.
• The tumor was mobile and did not directly obstruct cerebrospinal fluid (CSF) flow.
• Communicating hydrocephalus was present, indicated by increased intracranial pressure.

Findings:

• Computerized axial tomography (CAT) proved highly effective for diagnosis and monitoring.
• Complete tumor resection successfully resolved the hydrocephalus.
• No CSF shunt was required post-operatively.

Implications:

• This case highlights that excessive CSF production by choroid plexus papilloma can independently cause communicating hydrocephalus.
• Less invasive management may be possible in select cases, avoiding shunt placement.
• Further research into CSF hyperproduction mechanisms in pediatric brain tumors is warranted.
