Although its prognosis has improved with the development of chemotherapy regimens, the mortality rate of patients with brain metastases is reportedly 29.7% [2]. After chemotherapy, most often, the reappearance of masses in pulmonary is considered to be a sign of relapse. Case presentation: The patient was a 32-year-old Asian Chinese female who delivered a dead male infant at 33 weeks gestation. The placenta appeared to be normal. The major presentation was a haemorrhage of the vagina. The patient received combined treatment with systematic multi-agent chemotherapy and whole-brain radiation therapy at the General Hospital of Hebei Province and achieved complete remission. Two years after remission, a chest CT scan revealed a mass in the right lung that had become larger over 6 months. The patient’s serum β-human chorionic gonadotropin (β-HCG) level was normal, and the tuberculosis infected T lymphocyte spot (T-SPOT.TB) tests were positive. The patient was started on anti-tuberculosis therapy, after which the size of her right lung mass decreased. Conclusion: Lung masses after choriocarcinoma require extensive laboratory and imaging exams to exclude recurrence. This case highlights the importance of differential diagnoses of lung masses in patients with choriocarcinomas. Imaging studies, β-HCG and local lesion resection should be employed to rule out choriocarcinoma recurrence.展开更多
