A Rare Case of Non-Gestational Metastatic Ovarian Choriocarcinoma: Case Report and Literature Review With a Special Emphasis on Imaging

摘要

Non-gestational choriocarcinoma of the ovary is a very rare neoplasm. It carries a worse prognosis as compared to gestational choriocarcinoma (GCC). Here, we report a case of non-gestational ovarian choriocarcinoma. The patient initially presented in a medical emergency with abdominal pain, a feeling of heaviness in the lower abdomen, cough, and dyspnea. The patient had four healthy children, and the last childbirth was five years ago. There was no history of any abortion or stillbirth in the past four years. A highly vascular left adnexal mass?was observed on ultrasound abdomen and pelvis. Compute CT chest, abdomen, and pelvis were performed, which revealed metastatic left ovarian choriocarcinoma features. It also showed?vascular metastases of the carcinoma in the kidneys, liver, and lungs. We report this case specifically emphasizing ultrasound, multidetector computed tomography (MDCT), and CT angiography findings.
