Summary
This case report details a rare pineal region choriocarcinoma in a child, diagnosed years after initial symptoms. Early detection via imaging and hormonal tests, followed by surgery and chemotherapy, led to a favorable outcome.
Area of Science:
- Neuro-oncology
- Pediatric Endocrinology
- Medical Imaging
Background:
- Primary choriocarcinoma is a rare germ cell tumor, particularly in the pineal region.
- Precocious puberty can be an early sign of a pineal region tumor.
Observation:
- A six-year-old boy presented with precocious puberty, followed by sudden coma due to ventricular hemorrhage.
- Initial clinical, hormonal, and neuroradiological evaluations were inconclusive.
- A pineal region tumor and elevated serum human chorionic gonadotropin (HCG) were detected four years later via CT and hormonal assays.
Findings:
- The tumor exhibited characteristics of choriocarcinoma with syncytiotrophoblast and cellular trophoblast, showing strong HCG activity.
- Subtotal tumor removal was achieved using Stein's supracerebellar infratentorial approach.
- Postoperative chemotherapy with actinomycin-D and methotrexate normalized serum HCG levels.
Implications:
- Early diagnosis of pineal region tumors is crucial, utilizing advanced imaging and hormonal markers.
- Prompt treatment, including surgery and chemotherapy, can prevent severe complications like hemorrhage and improve prognosis.
- This case highlights the importance of considering rare diagnoses in pediatric oncology.
