Choriocarcinoma is the most malignant tumour of gestational trophoblastic origin. Most ovarian choriocarcinomas are gestational in origin and usually metastasize to the ovary from uterine or tubal choriocarcinoma. Non gestational choriocarcinoma (NGOC) of the ovary is exceedingly rare and usually seen along with other germ cell tumors. Non gestational choriocarcinoma has been found to be resistant to single-agent chemotherapy and has a worse prognosis than gestational choriocarcinoma. We are reporting long term follow up of published rare case of pure non gestational ovarian choriocarcinoma (NGOC) with concurrent metastases to the spleen and adrenal glands, who developed a delayed solitary brain metastases, two years after completion of primary treatment. Surgery along with triple agent chemotherapy and radiotherapy was found to give good remission in this aggressive disease.
