摘要Background:Chorionic carcinoma is a highly malignant gynecological tumor,frequently originating from trophoblastic cells in the uterus after fertilization.Early erosion releases cancerous cells into the circulation to invade surrounding organs without primary symptoms and signs.Methods:One case of choriocarcinoma sellar region metastasis was analyzed,utilizing clinical data,MRI and pathological examinations,and clinical characteristics were summarized.Results:Choriocarcinoma sellar region metastasis is easily misdiagnosed.We examined the literature and original resources to summarize the clinical characteristics of choriocarcinoma sellar region metastasis and discuss available therapies.Conclusion:This case study of a metastasis of choriocarcinoma to the sellar region provides important new data on the incidence and pathology of this rare disease.
