“…In comparison to COD, the lesion presents a narrow more uniform, partial or complete, radiolucent border representing soft tissue encapsulation [21,22]. A reactive front of sclerosis may be present at the interface with the adjacent normal bone, especially in the slower growing COF [23,24]. The internal density and pattern is variable dependent on the maturity of the lesion and the amount and type of calcification.…”

Benign fibro-osseous lesions (BFOLs) are a particularly challenging set of diagnoses for the pathologist. This diverse collection of diseases includes fibrous dysplasia, ossifying fibroma and cemento-osseous dysplasia. While all three conditions have similar microscopic presentations, their treatment and prognosis differ, demanding an accurate and definitive diagnosis. A practical and systematic approach considering the patient's history, demographics, intraoperative presentation, and gross appearance with an emphasis on radiology and histology will be discussed.

“…It typically affects the mandibular bone, whereas sphenoid involvement is rare [ 59 ]. Ossifying fibroma is characterised by rapid growth, high recurrence rate (30–56%), a tendency to invade surrounding tissues — including the orbits — and bony erosions [ 60 ]. Imaging appearance varies according to the fibrous/bone tissue ratio within the lesion: in the early stages, a thick peripheral bony rim is observed which surrounds a fibrous soft tissue centre, whereas in the later stages, a progressive filling of this centre with mature bone can be detected [ 61 ].…”

A practical overview of CT and MRI features of developmental, inflammatory, and neoplastic lesions of the sphenoid body and clivus

The sphenoid bone is an unpaired bone that contributes to the formation of the skull base. Despite the enormous progress in transnasal endoscopic visualisation, imaging techniques remain the cornerstones to characterise any pathological condition arising in this area. In the present review, we offer a bird’s-eye view of the developmental, inflammatory, and neoplastic alterations affecting the sphenoid body and clivus, with the aim to propose a practical diagnostic aid for radiologists based on clinico-epidemiological, computed tomography, and magnetic resonance imaging features.

“…Cemento-ossifying fibroma commonly has a ground-glass appearance, but large lesions have a heterogeneous appearance (Figure 6). [36][37][38][39][40] The trabecular or psammomatoid variant of juvenile ossifying fibroma is less common than cementoossifying fibroma. Juvenile trabecular ossifying fibroma reported in adolescents (aged 9-12 years) is commonly found in the maxilla.…”

Bone-related disorders of the jaw: A clinico-radiological diagnostic algorithm

Bone-related disorders of the jaw (BRDJ) include a spectrum of non-neoplastic and neoplastic lesions of the maxillofacial region that have been recently classified into fibro-osseous lesions, giant cell lesions and osseous tumours. The histopathological features of BRDJ can be similar and overlie each other. Imaging is important in order to reach a specific diagnosis. However, the appearance of BRDJ on imaging is non-specific in some cases. Computed tomography (CT) and magnetic resonance imaging (MRI) are used for accurate localisation, characterisation of the tumour matrix, delineation of the lesion extension and establishment of the relation of BRDJ to the surrounding structures. Imaging is usually done to detect the relationship with the adjacent surrounding vital structures and to diagnose aggressive forms, malignant transformation and associated syndromes. The correlation of the demographic findings, the location and the clinical presentations with the imaging features are important for the diagnosis of BRDJ. The proposed clinico-radiological diagnostic algorithm with CT and MRI helps a specific diagnosis to be reached in some cases.

CT and MR imaging characteristics of histological subtypes of head and neck ossifying fibroma

Abstract: COFs tended to exhibit well-defined margins and preserved continuity of the overlying bone cortex. COFs were usually homogeneous, whereas JPOFs and JTOF were always heterogeneous. Target-like appearance was one of the characteristics of OFs, but it was observed in both COF and JPOF.
