[A case of asymptomatic posterior mediastinal pheochromocytoma diagnosed during the procedure of video-assisted thoracic surgery (VATS)].
The patient was a 20-year-old male. On routine check-ups, a posterior mediastinal tumor was found radiologically and referred to our hospital for the operation. During the Video-Assisted Thoracic Surgery (VATS), sudden elevation of the blood pressure up to 270 mmHg was observed by the tumor palpation. At once we diagnosed as pheochromocytoma. Changing the VATS to usual thoracotomy the tumor was completely removed and histologically confirmed. After the operation the patient was uneventful and the value of norèpinephrine reduced to normal range from 2912 pg/ml. The posterior mediastinal pheochromocytoma is rare and this report is the 6 th case in Japan. Clinical characteristics were discussed in addition to the review of the literature.
