A 54-year-old otherwise healthy male presented with a posterior cervical growing tumor (Figure 1A). Although there was no pain associated with the tumor, it had been growing at a regular pace and the patient had been experiencing symptoms for 1 year. Clinical examination revealed a mobile soft mass. We found no cervical, supraclavicular, or axillary node. A magnetic resonance image of the neck showed a 150-mm long, well-defined tumor. The axial Tl image with fat suppression (Figure 1B1) and the sagittal T2-weighted magnetic resonance image (Figure 1B2) not only demonstrate a large lobulated mass that predominantly demonstrates a high T2-signal intensity, but also contains septa that demonstrates intermediate signal intensity.
