Figure 1.

A 21-year-old man with plexiforma neurofibroma in the right cranio-maxillofacial region. (A) Non-enhanced CT demonstrates a giant cystic-solid mass in the right craniomaxillofacial region, and the cyst of the mass appearing as hyper- and iso- attenuation (white arrows). (B) Contrast-enhanced CT depicts the mass appearing as no enhancement (arrows). (C) SSD reconstruction CT shows the cosmetic impairment of right face. (D) On T1-weighted MR image, the cyst of the mass shows heterogeneously intermediate to high signal intensity (arrows). (E) The cyst of the mass shows light low to intermediate signal intensity on T2 weighted MR image (arrowhead) with a low-signal ring around the hematoma (thin arrows).
