    Area of Science:

    • Neuro-oncology
    • Pediatric oncology
    • Ophthalmology

    Background:

    • Chiasmal ependymomas are rare central nervous system tumors.
    • Malignant variants present unique diagnostic and therapeutic challenges.

    Observation:

    • A 15-year-old male presented with a suspected chiasmal mass.
    • Initial diagnosis was unsuspected until histological confirmation via biopsy.
    • The tumor showed transient improvement after irradiation therapy.

    Findings:

    • A significant tumor recurrence demonstrated a dramatic response to PCV chemotherapy (procarbazine, lomustine, and vincristine).
    • PCV chemotherapy was administered in an outpatient setting with low morbidity.
    • This case highlights a potential effective treatment for recurrent chiasmal ependymoma.
