Rare Presentation of Rosai-Dorfman Disease in Soft Tissue: Diagnostic Findings and Surgical Treatment

Figure 3

Representative 9-month postoperative 1.5 Tesla MRI images. (a) T1 sagittal (TR 500 ms, TE 17 ms). (b) T2 FS sagittal (TR 4,770 ms, TE 83 ms). (c) T1 axial (TR 600 ms, TE 19 ms). (d) T2 FS axial (TR 6,580 ms, TE 100 ms). These images revealed a large T1 hypointense, T2 heterogeneously hyperintense, and enhancing lesion with irregular borders, measuring approximately 21.5 × 7 × 15 cm (transverse × anteroposterior × craniocaudal). There was a central stellate/spiculated portion of the lesion, which was a relatively nonenhancing region and suggestive of an area of postsurgical scarring. Surrounding this region was a more T2 hyperintense multilobulated appearing component. No other lesions were seen. FS = fat suppression, TR = repetition time, and TE = echo time.
