  		Figure 1. Frontal chest radiograph shows a well-marginated round mass in the right apical portion without bone change. Left paratracheal widening with deviation of the trachea to the right side is also seen, due to left lower neck and left paratracheal masses.

  		Figure 2. Axial(a–c) and coronal reformatted (d,e) CT scans show three well-defined masses in the left lower cervical (arrowheads), left paratracheal (long arrows) and right paravertebral (arrows) regions in the distribution of left vagus nerve, left recurrent laryngeal nerve and right paravertebral sympathetic chain, with poor and heterogeneous contrast enhancement.

  		Figure 3. Axial and coronal positron emission tomography (PET) (a–e) and PET/CT fusion (f–j) images reveal varying degrees of F-18 fluorodeoxyglucose (FDG) uptake in three masses, with SUVmax values of 5.3, 1.8 and 3.2 for left lower cervical, left paratracheal (long arrows) and right paravertebral masses, respectively.

  		Figure 4. Surgical specimen of three masses. The left lower cervical mass is spindle shaped, the left paratracheal mass is lobulated and the right paravertebral mass is ovoid. All masses had a hard consistency and were pseudocapsulated. Arrows indicate the partially resected vagus nerve.

  		Figure 5. Histological findings of three neurofibromas.(a) The left lower cervical neurofibroma, corresponding to the mass on Figure 3a, d, fGo and i, shows dense collagen bundles with increased cellularity (haematoxylin and eosin, original magnification x100). (b) The left paratracheal neurofibroma, corresponding to the mass with arrows on Figure 3c, e, h and jGo, has loose myxoid matrix containing neoplastic cells that are elongated and wavy (haematoxylin and eosin, original magnification x100). (c,d) The right paravertebral tumour, corresponding to the tumour in Figure 3b, e, g and jGo, contains the central zone of loose myxoid matrix (c) and the peripheral zone of markedly increased cellularity (d) (haematoxylin and eosin, original magnification x100). Focal mitotic activity (arrow in the interposition, haematoxylin and eosin, original magnification x400) is noted without nuclear atypia.
