Management problems in a case of third ventricular choroid plexus papilloma

Area of Science:

• Neurosurgery
• Pediatric Oncology
• Neuropathology

Background:

• Choroid plexus papillomas (CPPs) are rare tumors, typically occurring in the fourth ventricle, but can arise in the third ventricle.
• Hydrocephalus is a common complication, often managed with cerebrospinal fluid (CSF) shunting.
• Shunt ascites is a rare but serious complication of CSF shunting.

Observation:

• This report details a rare case of a third ventricular choroid plexus papilloma.
• The patient developed shunt ascites, a complication attributed to the CSF shunt.
• The tumor was surgically removed.

Findings:

• Complete tumor removal was achieved.
• The shunt was converted to a ventricular drain during the management of shunt ascites.
• The need for a permanent shunt was reassessed post-tumor resection.

Implications:

• This case highlights the importance of considering shunt-related complications in patients with third ventricular tumors.
• The proposed management strategy of converting to a ventricular drain may be effective in managing shunt ascites in this context.
• Further evaluation is needed to determine the long-term necessity of shunting after complete tumor resection.
