Imaging characteristics of orbital peripheral nerve sheath tumors: Analysis of 34 cases

Figure 2 Case 2, 53-year-old female, left orbital myxoid neurofibroma. A: A non-uniform density mass of left orbit with a size of 33 mm × 30 mm × 21 mm was displayed by computed tomography (CT) (as shown by the arrow); the CT value was 21-60 Hu; B-E: Magnetic resonance imaging showed that the focus, which was mainly cystic (long T1 and T2 signals), was located in the extrapyramidal space above the left orbit (as shown by the arrow); "V" shaped nerve fibers were observed (equal T1 and T2 signals); on contrast-enhanced scan, the cystic part was not enhanced, while the solid part showed continuous and obvious enhancement; F: Microscopically, there is a large amount of mucus around nerve fiber cells.
