Rare recurrent ovarian cancer presented with solitary mediastinal lymph node involvement and diagnosed by transbronchial needle aspiration: a case report

Abstract

We report a case of ovarian cancer with post operative solitary mediastinal lymph node metastasis, which was diagnosed by transbronchial needle aspiration (TBNA). A 64 year-old female was referred to hospital with a complaint of menorrhea. Serum CA125 titre was more than 500 U/mL. Surgical resection was undertaken based on MRI, suggesting it's an ovarian cancer. Subsequently, she underwent postoperative-chemotherapy and a follow-up. 2 years post operatively, the only clinical abnormality was a solitary enlarged mediastinal lymph node and increase in the levels of serum CA125. TBNA was performed, and cytology revealed an adenocarcinoma. We diagnosed the patient to recurrence of ovarian cancer, which exhibited solitary mediastinal lymph node enlargement.
