Patient
female, 67 year(s)
 
 
  • Figure 1
    MRT1w axial imaging of region of patient complaints (blue-arrow).

    Heterogeneous lesion deep in scapular region muscles and anterior to the inferior pole of the scapula. Signal intensity similar to muscle with some linear interlaced areas of signal intensity similar to fat (red arrow).

     
    Area of Interest: Musculoskeletal soft tissue; Soft tissues / Skin; Thoracic wall; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Dysplasias; Metastases; Neoplasia;
     
     
  • Figure 2
    MR-T2w axial imaging in the region of patient complaints

    The findings were the same as in the previous figure (heterogeneous lesion with intensity signal similar to muscle tissue with some interlaced linear areas of signal intensity similar to fat).

     
    Area of Interest: Musculoskeletal soft tissue; Soft tissues / Skin; Thoracic wall; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Dysplasias; Metastases; Neoplasia;
     
     
  • Figure 3
    MR-STIR axial imaging at the same level of previous figures

    The hyperintense linear areas seen in the previous sequences (red arrow), loose signal with fat-suppression techniques, indicating the presence of fat components within the lesion.

     
    Area of Interest: Musculoskeletal soft tissue; Soft tissues / Skin; Thoracic wall; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Dysplasias; Metastases; Neoplasia;
     
     
  • Figure 4
    T2w axial MR imaging with a larger FOV.

    A similar lesion in the opposite side was found (green arrow).
