A female in her 70s underwent total hysterectomy and bilateral adnexal resection for clear-cell ovarian cancer, and right anterior chest pain developed one year after the operation. Computed tomography (CT) showed a 10-mm nodular shadow on the first to third intercostals adjacent to the right sternum and a nodular shadow on the upper lobe of the right lung. Accumulation of 18-fluorodeoxyglucose (FDG) was observed on positron emission tomography (PET)-CT, and ovarian cancer metastasis to the chest wall and lung was suspected. The thoracic wall lesions had a relatively clear margin, and no FDG-accumulation in the ribs nor sternum was observed. Wedge lung resection and excision of the parasternal lesions were performed under 3-port video-assisted thoracoscopic surgery. The resected lesion was diagnosed as ovarian cancer metastasis by pathological examination. There have been few reports on patients with parasternal metastases from ovarian cancer. Under such conditions, cancer cells that disseminate in the peritoneum metastasize to the lymph nodes through the diaphragm, possibly via the lymphatic system and subsequently to the parathoracic lymph nodes.
