Ovarian choriocarcinoma is a rare and highly malignant tumor characterized by the presence of malignant trophoblastic cells that produce human chorionic gonadotropins (hCG). This type of cancer can be classified into gestational and non-gestational forms, with the latter being extremely uncommon. The standard treatment for gestational choriocarcinoma involves methotrexate-based chemotherapy. This case study presents a rare instance of ovarian choriocarcinoma managed through surgical resection followed by methotrexate chemotherapy. The study aims to evaluate the ultrasound characteristics of ovarian choriocarcinoma and the diagnostic approach.
In this case, the presence of an elevated serum beta-hCG level prompted further investigation through ultrasound. The ultrasound evaluation revealed a highly vascularized adnexal mass, which is a critical finding for suspecting choriocarcinoma. This is particularly relevant in young females with no marital history or sexual intercourse, as well as in married women with histories of repeated abortions, molar pregnancies, or uterine choriocarcinoma. Recognizing these ultrasound characteristics is vital for timely diagnosis and intervention, given the aggressive nature of this malignancy. The findings underscore the importance of ultrasound as a diagnostic tool in identifying ovarian choriocarcinoma, allowing for early surgical and chemotherapeutic management. This case serves as a reminder of the rarity of ovarian choriocarcinoma and the need for heightened awareness among clinicians when interpreting ultrasound findings in at-risk populations.
