CT scan may be helpful in the diagnosis of fibroma. Findings on CT suggestive of a particular fibroma depends on the type of the fibroma. Findings on CT scan of ossifying fibroma include a well-circumscribed lesion, intracortical osteolysis with a characteristic sclerotic band, and moderate cortical expansion. Findings on CT scan of non- ossifying fibroma include sharply demarcated, asymmetrical, cortically based lucencies with a thin sclerotic rim. Findings on CT scan of chondromyxoid fibroma include a mild cortical expansion and characteristic lack of mineralization within chondromyxoid fibroma. Findings on CT scan of cemento-ossifying fibroma include a well circumscribed masses which expand the underlying bone.

CT Findings

Ossifying Fibroma

Findings on CT scan of ossifying fibroma includes the following:[1][2][3]

  • Seen as a well-circumscribed lesion
  • Demonstrates evidence of intracortical osteolysis with a characteristic sclerotic band (osteoblastic rimming)
  • Moderate cortical expansion

Non-ossifying Fibroma

Ovarian Fibromas

  • They usually manifest as diffuse, slightly hypoattenuating masses with poor, very slow contrast enhancement. Calcification and bilaterality are both uncommon.[5][6][7]

Pleural Fibromas

Pleural fibroma: (A) Chest radiograph showing lobulated pleural-based opacity (arrow) in right apical region; (B) axial contrast-enhanced CT scan showing heterogeneously enhancing peripheral mass lesion (arrow) in a biopsy-proven case of benign pleural fibroma,Sureka B, Thukral BB, Mittal MK, Mittal A, Sinha M. Radiological review of pleural tumors. Indian J Radiol Imaging. 2013;23(4):313–320. doi:10.4103/0971-3026.125577,

Cardiac Fibromas

Chondromyxoid Fibroma

Cemento-ossifying Fibroma

  • Cemento-ossifying fibromas are usually well circumscribed masses which expand the underlying bone.
  • They are usually small, but can become large. This is particularly the case when they arise from the maxilla or paranasal sinuses because there is more room to expand.
  • As they mature, they gradually develop increasing amounts of calcification/ossification as they mature.
  • They usually expand the bone without cortical breach.
  • Following administration of contrast, the soft tissue component usually enhances on CT.

Uterine Fibroma

  • They may distort the usually smooth uterine contour
  • Enhancement pattern is variable
