[Interlobar neurinoma with a cystic formation derived from the vagal pulmonary branches].

A 60-year-old woman was referred to our hospital because of an abnormal shadow in the chest roentgenogram. Chest computed tomography (CT) showed the mass with heterogeneous low attenuation in the right lower lobe (S6), 40 mm in size. Fluorodeoxyglucose-positron emission tomography (FDGPET)/CT scanning revealed slight positive reaction in the right lower lobe lesion. The video-assisted thoracoscopic surgery (VATS) was performed to establish diagnosis and treat. Intraoperative finding showed the tumor was located between the left upper lobe and the left lower lobe, and the inflow of the vagal pulmonary branches. Histopathological examination showed no malignancy and neurinoma with a cystic formation derived from the vagus nerve.
