Ruptured cerebral aneurysm from choriocarcinoma

Area of Science:

• Gynecology
• Oncology
• Neurology

Background:

• Gestational trophoblastic diseases encompass a spectrum of placental-related lesions, including choriocarcinoma.
• Choriocarcinoma, a rare malignancy, originates from placental trophoblastic epithelium and can metastasize.
• Brain metastasis is a significant complication, impacting prognosis in gestational choriocarcinoma.

Observation:

• This study details a unique case of metastatic choriocarcinoma presenting as an intracerebral hematoma.
• The hematoma resulted from an oncotic aneurysm, a rare complication of choriocarcinoma metastasis.
• Notably, the patient presented with normal serum beta-human chorionic gonadotropin (β-HCG) levels, challenging typical diagnostic markers.

Findings:

• Intracranial choriocarcinoma can present with intracerebral hemorrhage due to oncotic aneurysms.
• Normal serum β-HCG levels do not exclude the possibility of metastatic choriocarcinoma, particularly in the central nervous system.
• This case highlights the diagnostic challenges posed by atypical presentations of choriocarcinoma.

Implications:

• Clinicians should consider metastatic choriocarcinoma in the differential diagnosis of intracerebral hemorrhage, even with normal serum β-HCG.
• Further research is needed to understand the mechanisms and diagnostic criteria for choriocarcinoma presenting with normal β-HCG.
• This case underscores the importance of comprehensive diagnostic evaluation in complex neurological presentations potentially linked to gestational trophoblastic disease.
