Abstract
OBJECTIVE: Non-gestational choriocarcinoma (NGC) is a rare germ cell tumor, reported less than 0.6% of all gestational tumors, and has a poor prognosis when metastasized. NGC is even less reported with metastasis to the brain. Gestational choriocarcinoma (GC) when metastasized to the brain has a higher morbidity and mortality but has been known to be a chemosensitive and radiosensitive lesion, and NGC is chemoresistant with an even worse prognosis. Currently, there is no consensus for treatment for metastatic NGC to the brain.
CASE DESCRIPTION: 66 year-old post-menopausal female presents with left upper extremity weakness more pronounced in her hand, and work up demonstrating a hemorrhagic lesion over the right frontal parietal lobe. Her metastatic work up was negative, leading to a craniotomy for resection of the mass. The pathology was consistent with metastatic gestational choriocarcinoma, non-gestational in origin.
CONCLUSIONS: Because of its chemosensitive nature, reports of optimal metastatic GC treatment include radiation alone, chemotherapy without radiation, surgical resection, or combined multimodal therapy. No recommendations for NGC metastatic to the brain have been reported. We propose a systematic work up for hemorrhagic brain lesions to include the proposed imaging modalities and serum markers including β-hCG to aid with early diagnosis. With review of literature, we recommend surgical resection with adjuvant therapy for accessible symptomatic metastatic GC and NGC to the brain for optimal patient outcomes. Chemotherapy and radiation alone without surgical resection can be considered for asymptomatic GC metastasis to the brain.
