3

Ventriculoperitoneal Shunt Placement

Surgical placement of shunt to manage hydrocephalus that commonly accompanies choroid plexus tumors. Addresses symptoms of increased intracranial pressure and may be temporary or permanent depending on response.

Additional treatment options

Adjuvant Radiation Therapy

Radiation therapy for malignant choroid plexus neoplasms, particularly when complete resection is not possible or for high-grade lesions. Advanced techniques like proton therapy may reduce collateral damage.

procedure

Chemotherapy for Carcinoma

Multi-agent chemotherapy may be recommended for choroid plexus carcinoma, particularly in pediatric patients to delay or avoid radiation. Adult regimens may vary and require individualized planning.
