Primary intracranial choriocarcinoma

Area of Science:

• Neuro-oncology
• Endocrinology
• Pathology

Background:

• Primary intracranial choriocarcinoma is an extremely rare germ cell tumor.
• This condition predominantly affects young males and can present with varied neurological and endocrine symptoms.

Observation:

• Four cases in young males are presented, with tumors located in the pineal region and lateral ventricle.
• Clinical manifestations included increased intracranial pressure, ophthalmological issues, skin changes, and precocious puberty.
• Radiological findings showed characteristic tumor staining and enhanced CT scan features.

Findings:

• Hormonal studies confirmed elevated human chorionic gonadotropin (HCG) and luteinizing hormone (LH) levels in serum, CSF, and tumor tissue, indicating intrinsic HCG secretion by tumor cells.
• Tumors were hemorrhagic and relatively well-demarcated.
• Successful treatment was achieved in two cases using a multimodal approach.

Implications:

• This study highlights the importance of hormonal evaluation in diagnosing intracranial choriocarcinoma.
• Early diagnosis and multimodal treatment, including surgery, chemotherapy, and radiation, can lead to favorable outcomes.
• Understanding the endocrine activity of these tumors is crucial for effective management.
