Figure 1. (a) A computed tomography image showing multiple masses with homogeneous density and no bone destruction, with a maximum size of 7.0 × 6.1 cm. (b) A T2-weighted magnetic resonance imaging scan showing a higher signal intensity, with the mass showing an uneven signal and well-defined margins. (c) A T1-weighted magnetic resonance imaging scan showing a slightly higher signal intensity, with the mass showing an uneven signal and liquefaction at the center.
Figure 2. Histological observations. (a) The largest excised specimen was dark gray and measured 7 × 6.5 × 4.5 cm. (b) Photomicrograph of the neurofibroma component showed papillary proliferation of cells with cystic degeneration and a lobular arrangement (hematoxylin-eosin staining; magnification, × 100). (c) The neurofibroma was composed of proliferating spindle cells containing bland cigar-shaped nuclei with inconspicuous nucleoli and an eosinophilic cytoplasm. The lobules in the masses comprised a tight swirl of cells, though the focal areas demonstrated closely clustered thin-spindled and stellate cells (hematoxylin-eosin staining; × 100).
