Ancient schwannoma of vagus nerve mimicking hamartoma.
Schwannomas arising from vagus nerve sheath are rare mediastinal neurogenic tumours. Schwannomas usually arise from left hemithorax. Unlike a hamartoma, radiologically, calcification is rarely seen in schwannomas. We present the rare case of an ancient schwannoma arising from vagus nerve sheath from the right hemithorax presenting with gross calcification.
متن کاملVagus nerve schwannoma in the right upper mediastinum
A 35-year-old woman was admitted to our hospital with an abnormal shadow on her chest roentgenogram. Computed tomography showed that a tumor was located in the right upper mediastinum. Resection of the tumor by video-assisted thoracoscopic surgery was performed. Operative findings determined that the tumor originated from the right vagus nerve and was diagnosed as schwannoma by pathological exa...
متن کاملCase of malignant transformation of vagus nerve schwannoma to angiosarcoma.
BACKGROUND It is known that benign tumors have the potential for malignant transformation. Malignant transformation of vagus nerve schwannoma to angiosarcoma is very rare. METHODS We report a case of malignant transformation in which the initial diagnosis was subsequently altered to angiosarcoma originating from the vagus nerve. We compared the findings of MRI and fine-needle aspiration (FNA)...
متن کاملCervico-mediastinal schwannoma of the vagus nerve: resection with intraoperative nerve monitoring.
Schwannomas are usually benign, single, encapsulated, slow-growing tumours originating from cranial or spinal nerve sheaths. The vagus nerve involvement at the mediastinal inlet is very uncommon. For anatomical reasons, the resection of cervical and mediastinal schwannoma of the vagus nerve has a high risk of vocal fold paralysis. We describe the case of a 67-year-old female with a cervico-medi...
متن کاملAncient schwannoma of the vagus nerve, resection with continuous monitoring of the inferior laryngeal nerve.
Schwannomas (neurinomas, neurilemmomas) are benign, single, slow-growing encapsulated tumors that originate in the sheath of cranial or spinal nerves, and that rarely undergo malignant transformation. Descriptions have shown that about 25% of cases occur in the head and neck; there are only 95 references of vagus nerve involvement. These tumors appear mostly between the third and fifth decades ...
