Overview

X-ray may be helpful in the diagnosis of fibroma. Findings on x-ray suggestive of a particular fibroma depends on the type of the fibroma. Findings on x-ray suggestive of non-ossifying fibromas include sharply demarcated, asymmetrical, and cortically based lucencies with a thin sclerotic rim. Findings on x-ray suggestive of ossifying fibroma include well-circumscribed lesion, intracortical osteolysis with a characteristic sclerotic band, cortical expansion, and a lytic thinning of the diaphyseal cortical bone with interspersed sclerosis. Findings on x-ray suggestive of chondromyxoid fibroma include a lobulated, eccentric radiolucent lesion. Findings on x-ray suggestive of desmoplastic fibroma include a lytic bone lesions with a geographic pattern of bone destruction and a narrow zone of transition and non-sclerotic margins.[1][1]

Ossifying Fibroma

The following radiographic features are noted on x-ray of ossifying fibroma:[2]

Chondromyxoid Fibroma

The following features are seen on plain radiograph of chondromyxoid fibromas:[3]

  • Chondromyxoid fibroma is seen as a lobulated, eccentric radiolucent lesion
  • Long axis is parallel to long axis of long bone
  • No periosteal reaction (unless a complicating fracture present)
  • In approximately 100% of cases geographic bone destruction is present
  • In approximately 85% of cases well defined sclerotic margin is present
  • In approximately 60% of cases there can be presence of septations (pseudo trabeculation)
  • In approximately 12.5% there can be presence of matrix calcification

Desmoplastic Fibroma

The following features are seen on plain radiograph of desmoplastic fibromas:[4]

X-ray revealed uneven density in the distal left femur, in which lamellate high-density opacity and bone destruction were observed.,Xu Y, Wang Y, Yan J, Bai X, Xing G.

Pleural Fibroma

Cemento-ossifying fibroma

  • The following features are seen on plain radiograph of cemento-ossifying fibromas:[6]

Uterine Fibromas

Non-ossifying Fibroma

  • On x-ray, non-ossifying fibromas are characterized by sharply demarcated, asymmetrical, cortically based lucencies with a thin sclerotic rim.[7]
  • They often appear multiloculated. They are located in the metaphysis, adjacent to the physis. As the patient ages, they seem to migrate away from the growth plate.
  • They have no associated periosteal reaction, cortical breach or associated soft tissue mass.
  • Nonossifying fibroma appear as well defined, small, eccentric, lytic, expansile lesions located in the metaphysis with scalloped sclerotic borders. Multiple lesions may be present.
