Malignant choroid plexus papilloma with extraneural metastasis. Case report
Journal of Neurosurgery
|February 1, 1980
Summary
This study details a rare malignant choroid plexus papilloma in an infant. The tumor showed unusual longevity and a probable metastatic spread, offering insights into rare pediatric brain tumors.
Area of Science:
- Pediatric neuro-oncology
- Neurosurgery
- Pathology
Background:
- Choroid plexus papillomas are rare tumors, typically benign, arising from the choroid plexus epithelium.
- Malignant variants (carcinomas) are aggressive and have a poor prognosis, especially in infants.
Observation:
- A case of malignant choroid plexus papilloma in an 11-month-old child is presented.
- The tumor originated in the lateral ventricle.
- Unusual features included a 9-year survival and an extraneural malignant deposit.
Findings:
- The malignant choroid plexus papilloma exhibited an exceptionally long survival period of 9 years.
- Evidence of extraneural spread, likely metastatic, was observed, which is uncommon for this tumor type.
Implications:
- This case expands the understanding of the clinical spectrum and potential behavior of malignant choroid plexus papillomas.
- Highlights the importance of considering metastatic potential even in rare pediatric brain tumors with prolonged survival.
