Popis: A 50-year-old man underwent repeat surgery for a benign vagal schwannoma in the middle mediastinum. He had undergone tumor enucleation at another hospital 4 months before presentation. The tumor (99 × 88 × 76 mm) was located in the aortopulmonary window and arose from the left vagus nerve. It had been enucleated, leaving its sheath behind to preserve the nerve. Imaging studies showed tumor regrowth without distant metastasis, and the tumor was extirpated along with the involved nerve during cardiopulmonary bypass. There was no nerve dysfunction, recurrence, or metastasis 6 months after the operation. A benign vagal schwannoma can be excised with nerve transection or enucleated without nerve transection. The present case suggests that a vagal mediastinal schwannoma should be extirpated along with the nerve because insufficient enucleation might lead to tumor regrowth.
