ABSTRACT
Horizontal stenting protects the aneurysm neck with stent deployment across the aneurysm neck via the circle of Willis. A saccular aneurysm associated with intracranial arterial fenestration is very rare. Herein, we describe the first case of an unruptured aneurysm related to intracranial arterial fenestration treated with horizontal stenting. A 23-year-old woman presented with a 7-mm broad-necked aneurysm at the fenestration of the right intracranial vertebral artery (VA), which was incidentally found on magnetic resonance imaging. The patient underwent endovascular treatment with horizontal stenting via the vertebrobasilar junction from the contralateral left VA, followed by coil embolization using a jailed microcatheter from the ipsilateral right VA. The procedure was finished with sufficient embolization, and no complications occurred. Horizontal stent delivery via the vertebrobasilar junction for coil embolization of a broad-necked aneurysm arising from the fenestration of the VA is a safe and effective therapeutic strategy.

Background: Brenner tumor is a rare epithelial ovarian neoplasm that accounts for 2-3% of all ovarian neoplasms. Herein, we report the first case of thoracic spinal metastasis of recurrent Brenner tumor without local recurrence.Case Description.A 70-year-old female presented with a feeling of abdominal distension. Computed tomography revealed cystic lesions in her bilateral ovaries. Blood examination revealed high CA-125 [74.9 U/ml]. We excised bilateral ovaries, uterus, and omentum. Borderline Brenner tumor was diagnosed [Ki-67 labeling index: 10 %]. Follow-up abdominal echo and CA-125 examination revealed no local recurrence. 26 months later she developed paraplegia. Magnetic resonance imaging revealed tumor in the 5th-9th thoracic vertebra and compression of spinal cord at the 6th thoracic vertebra level. Her paraplegia was progressive. We performed semi-urgent partial resection of tumor and release of spinal cord compression. Spinal metastasis from Brenner tumor was diagnosed [Ki-67 labeling index: 50-60 %]. She received adjuvant radiation of 30 Gy in 10 fractions to the 4th-10th thoracic vertebra. After radiation and rehabilitation, she was discharged home on foot. She received adjuvant radiation and chemotherapy but died 11 months after spinal surgery. An autopsy has not been performed on her, and the cause of death is unknown. Conclusion: We report the first case of thoracic metastasis of recurrent Brenner tumor without local recurrence.
