Typical magnetic resonance imaging (MRI) and pathological characteristics of elastofibroma dorsi. (A and B) A 64-year-old male patient presented with a mass in the right subscapular area. MRI revealed a lenticular-shaped mass appearing as low- to iso-intense on T1- and T2-weighted images, with high-intensity strands reflecting the fat tissue inside the tumor. (C) Gadolinium injection resulted in scattered enhancement within the tumor. (D) The mass is located between the serratus anterior muscle and the posterior thoracic wall on coronal view. (E and F) Hematoxylin and eosin staining revealed elastic and collagen fibers coexisting with mature adipose tissue. Arrowheads, tumor borders.
