[Neurogenic tumors originated from vagus nerve and intercostal nerve simultaneously; report of a case].

A 60-years-old man was presented with the posterior mediastinal tumor by chest computed tomography (CT) that had been taken for the examination of another disease. A well circumscribed mass of 9 x 6 x 5 cm in diameter between the body of the thoracic vertebra and pericardium and a well circumscribed mass of 2 x 2 x 0.8 cm in diameter in the 9th intercostal space were noted by chest CT. von Recklinghausen's disease was suspected by the presence of a lot of brown spots and subcutaneous small nodules in the whole body, and both was speculated as neurogenic tumors. Both tumors were removed by the operation, and the pathologic diagnosis of the neurofibroma was obtained.
