case_images: The patient underwent MRI and CT imaging of her right scapula which revealed an abnormal 5.3 x 4.7 cm soft tissue mass in the posterior medial aspect of the infraspinatus muscle. (see Figure 1) The mass was hypointense on T1, hyperinterense on T2, and was associated with prominent surrounding edema and significant infiltration into the surrounding soft tissue.

  of the PEComa after completion of neoadjuvant treatment (arrow). Edema of the surrounding
  infraspinatus muscle is evident as a bright area with less distinct boundaries
  than the tumor.
