Choroid plexus neoplasms show distinct differences between pediatric and adult patients. Outcomes are generally better in adults, with carcinomas more common in younger children.

Area of Science:

Neuro-oncology
Pediatric Neurosurgery
Neuropathology

Background:

Choroid plexus neoplasms are rare intracranial tumors with distinct pediatric and adult presentations.
Understanding these differences is crucial for effective management and prognosis.

Purpose of the Study:

To investigate differences in presentation, management, and outcomes of choroid plexus neoplasms between pediatric and adult populations.
To identify factors influencing patient outcomes and correlate clinical and histological findings.

Main Methods:

Retrospective review of 47 patients with choroid plexus neoplasms managed between 1984 and 2004.
Analysis of case records, images, histopathology, and follow-up data (41 patients).

Main Results:

60% of patients were pediatric, with 43% of children under 1 year old.
Lateral ventricle tumors were more common in children; fourth ventricle tumors in adults.
Calcification on CT was more frequent in papillomas and adult tumors.
Carcinomas were more prevalent in younger children.
Gross total excision was more feasible in adults; complications like subdural collections were more common in pediatric patients.
Invasion by nests of cells in papillomas did not portend a poor prognosis.

Conclusions:

Choroid plexus neoplasms exhibit significant differences between pediatric and adult populations.
Outcomes are generally better in adults, while carcinomas are more common in younger children.
Histological invasion patterns require careful interpretation for prognostic accuracy.
