Imaging findings
Shoulder radiograph shows a soft tissue abnormality with an incomplete border sign, suggesting an extrapleural or pleural-based lesion. Subsequent CT confirms a homogeneous, pleural-based lesion. Biopsy showed morphologic and immunotype features typical of a solitary fibrous tumor, positive for CD34.
Key takeaways
Solitary fibrous tumors of the pleura are typically pleural-based lesions that can present with an incomplete border sign on radiography. Immunohistochemistry (CD34 positivity) is characteristic. Most are benign, as in this case.
