Tubo-ovarian abscess is a rare but potentially serious event that can occur after uterine artery embolization (UAE). We describe herein two cases of severe inflammatory tubo-ovarian abscesses. Two women presented with severe abdominal pain, cramping, and fever several months after UAE. Abdominal computed tomography demonstrated an enlarged tubo-ovarian mass, suggestive of an abscess. Percutaneous catheter drainage was performed. In one patient, tubo-ovarian abscess completely disappeared after the drainage, but the other patient eventually required hysterectomy and salpingo-oophorectomy. It is important for clinicians to be aware of tubo-ovarian abscess as a rare complication. Percutaneous drainage might be a useful treatment option.

Cancer patients are at increased risk of thromboembolic events, and the combination of these two pathological conditions is known as Trousseau’s syndrome. Venous thromboembolisms (VTE) and pulmonary embolisms (PE) are the most common clinical features of Trousseau’s syndrome. However, arterial thromboembolisms can also occur. We report the case of a 55-year-old ovarian cancer patient, who developed repeated cerebral infarctions with catastrophic consequences. The initial ischemic stroke developed in the right middle cerebral artery territory 4 days before she was scheduled to undergo surgery. Anticoagulation therapy involving unfractionated heparin was administered, and the patient underwent emergency surgery, during which the right ovarian tumor was completely removed. Under a diagnosis of stage Ic ovarian cancer, postoperative adjuvant chemotherapy consisting of carboplatin plus paclitaxel was initiated. During the course of the adjuvant chemotherapy, the patient developed recurrent ovarian cancer, and second-line chemotherapy involving single agent gemcitabine was scheduled. After two months of second-line chemotherapy, which was not effective, the patient developed a second cerebral infarction in her left middle cerebral artery despite continuing to receive anticoagulation therapy. She died 5 days after the second stroke. Given the fact that recurrent thromboembolic events can occur even during ongoing anticoagulation therapy, intensive cancer treatment, thromboprophylaxis, and careful follow-up for the early detection of recurrent stroke events are recommended.
