Background: Primary choriocarcinoma of the pulmonary artery is an exceedingly rare malignant neoplasm, which is often misdiagnosed due to its nonspecific clinical presentation. While this condition is characterized by the presence of trophoblastic cells, typically associated with gestational trophoblastic diseases, we encountered a case occurring in an extragenital location. The rarity of such tumors makes it challenging for clinicians to consider them in differential diagnosis, especially when the initial symptoms mimic more common conditions such as pulmonary thromboembolism (PTE).

Here is such a case, in which suggestive imaging findings on [F]FDG PET/CT, a raised level of serum β-human chorionic gonadotropin, and gynecomastia clinched the diagnosis.

Non-gestational choriocarcinoma is an extremely rare and highly aggressive malignant tumor that arises independent of gestational events, making less than 0.6% of all ovarian germ cell tumors. Unlike the more common gestational choriocarcinoma, which is associated with pregnancy, non-gestational choriocarcinoma originates from germ cells within the ovary.
