Plexiform von Recklinghausen's Neurofibromatosis with Mediastinal Involvement-A Case Report

A 21-year-old male was admitted to our hospital because of an abnormal shadow on chest X-ray (CXR) noted during a routine military health check-up. He was asymptomatic and had no neurologic dysfunction. CXR showed widening of the upper mediastinum. Chest computed tomography scan demonstrated diffuse low-attenuation mass-like lesions on multiple compartments of the mediastinum, with cephalic extension to the lower neck and downward extension to the subdiaphragmatic paraaortic area. Mediastinoscopic biopsy disclosed a plexiform neurofibroma. During 2 years of follow-up, the patient was asymptomatic and stable, based on the radiographic results. We report this rare case of plexiform neurofibromatosis with mediastinal involvement.
