[edit] Discussion

  • Most patients are asymptomatic
  • The lesion is usually discovered incidentally on chest radiographs.
  • The tumor may become large, occupying much of the hemithorax.
  • When present, symptoms are usually related to the local mass effect of large lesions or to the associated paraneoplastic phenomena.
  • Paraneoplastic manifestations include hypertrophic osteoarthropathy and hypoglycemia.
  • Surgery is usually curative.
  • Formerly named "benign solitary fibrous tumor of the pleura" but named changed as some of these lesions are malignant.

[edit] Imaging Findings

[edit] Radiographs

  • Typically demonstrate a well-defined solitary peripheral mass,

[edit] CT

  • Typically demonstrates well-defined lobular borders, acute angles with the adjacent pleural surfaces, and heterogeneous enhancement after contrast administration.
  • Calcification is seen in approximately 25% of cases.

[edit] MRI

  • Heterogeneous signal intensity on both T1- and T2-weighted images.
  • May show internal flow voids corresponding to the vascular nature of the tumors.
