We report a rare case of 16-year-old boy who was given a diagnosis vasculo-Behçet disease after removing a right atrial thrombus. He was admitted to our hospital with abdominal pain and fever. He was underwent appendectomy for suspected appendicitis, but the appendix was normal. Additional image examinations revealed a mobile right atrial mass and inferior vena cava thrombosis, and the patient was sent to reoperation urgently to prevent pulmonary embolism. Surgery revealed the mass to be a thrombus. Vasculo-Behçet disease was diagnosed based on the patient's history and examination data. He was discharged on the 17th postoperative day. Cardiac mass excision should be immediately considered in such cases, and the differential diagnosis of Behçet disease was important for this case.

We report a rare case of type A acute aortic dissection with paraplegia which was cured immediately after an emergency operation. A 79-year-old woman was transferred to our institution with sudden back pain and paraplegia. Computed tomographic scans revealed a cardiac tamponade with an acute type A aortic dissection. She went into shock soon after arrival, and about 4 hours from onset we performed an emergency replacement of the ascending aorta. Three hours after the operation, her neurological deficit gradually resolved and could walk by postoperative day 3. This case suggests that early restoration of the blood flow to the spinal cord is mandatory to relieve paraplegia caused by type A aortic dissection.
