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:

Chondromyxoid Fibroma

The following features are seen on plain radiograph of chondromyxoid fibromas:[2]

  • 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:[3]

    X-Ray

    Non-ossifying Fibroma

    • On X-Ray, non-ossifying fibromas are characterized by sharply demarcated, asymmetrical, cortically based lucencies with a thin sclerotic rim.
    • 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.<ref name="pmid12544273">Yildiz C, Erler K, Atesalp AS, Basbozkurt M (2003). "Benign bone tumors in children". Curr Opin Pediatr. 15 (1): 58–67. PMID 12544273.
