Non-ossifying fibromas have the following features (all shown here): present in adolescents and young adults..
A non-ossifying fibroma usually produces no symptoms. It usually resolves by itself. It never spreads. Its cause is unknown. It's often discovered by chance on an X-ray. Surgery is only necessary of it causes a fracture or weakens the bone. What is the long-term outlook for a child with a non-ossifying fibroma? Prognosis for a non-ossifying. Called nonossifying fibroma if loose, > 5 cm and associated with intramedullary component Distinctive lesions in teenagers, no gender preference Benign; asymptomatic except for possibly pain Probably a developmental defect (not neoplastic), usually resolves in a few years and is replaced by cortical bon Potential diagnoses were Aneurismal bone cyst, Enchondroma, Nonossifying fibroma, Giant cell tumour and Osteosarcoma. Discussion Nonossifying fibromas and fibrous cortical defects are among the most common benign bone tumours in childhood and adolescence, usually detected by radiographs taken for an unrelated reason [1,2,3,4] CASE 54 Nonossifying Fibroma. George Nomikos, Anthony G. Ryan, Peter L. Munk, and Mark Murphey. Clinical Presentation. A 15-year-old girl presented with ankle pain PURPOSE: To correlate the findings of nonossifying fibroma at magnetic resonance (MR) imaging with those at pathologic examination.

Bone tumor - Differential diagnosis and Systematic approach Henk Jan van der Woude and Robin Smithuis Radiology department of the Onze Lieve Vrouwe Gasthuis, Amsterdam and the Rijnland hospital, Leiderdorp, the Netherland Patient underwent surgery. A fibrous lesion was found in the left distal femur which was curetted and a diagnosis of non-ossifying fibroma was made on histopathology. Non-ossifying fibroma, is the commonest non-neoplastic fibrous osseous lesion,..
The aim of this study was to assess and present the radiological morphology of the non-ossifying fibroma (NOF), to describe the life span according to the Ritschl-stages in an effort to determine critical stages with regard to pathological fractures and discuss the need for a follow-up. Reports of a consecutive series of 87 patients with 103 NOFs and a mean follow-up of 27 months were analysed. The term ossifying fibroma has been used since 1927, and since 1968 cementum-containing tumours have been grouped together. 1 In 1971 the World Health Organization (WHO) classified four types of cementum-containing lesions: fibrous dysplasia, ossifying fibroma, cementifying fibroma and cemento-ossifying fibroma. 4 According to the second WHO classification, benign fibro-osseous lesions.

PURPOSE: To correlate the findings of nonossifying fibroma at magnetic resonance (MR) imaging with those at pathologic examination. MATERIALS AND METHODS: In 19 patients (age range, 8-25 years; mean age 14 years) with pathologically proved nonossifying fibroma, MR images were analyzed for signal intensity and patterns of contrast enhancement The non-ossifying fibroma (NOF) is a benign osseous lesion that is a subtype within a spectrum of multiple fibrous osseous lesions. It is common within the pediatric population and some studies suggest that as much as 33% of all normal children may have one or more undetected small fibrous cortical defects [1,2] The terms fibroxanthoma, nonossifying fibroma (NOF), fibrous cortical defect (FCD), and, less commonly, benign fibrous histiocytoma have all been used interchangeably in the radiology literature. The non-ossifying fibroma (NOF) and the fibrous cortical defect (FCD), however, are considered to be 2 distinct lesions with respect to size and natural history General Considerations. Also called a non-ossifying fibroma or fibrous cortical defect. Non-ossifying fibroma frequently reserved for lesions > 2cm in size in older children; Usually arises in metaphysis of distal femur or tibi A nonossifying fibroma is a common benign bone tumor in children and adolescents.However, it is controversial whether it represents a true neoplasm or rather a developmental disorder of growing bone. Radiographically, the tumor presents as a well marginated radiolucent lesion, with a distinct multilocular appearance
The incidence of Non ossifying fibroma is approximately 1000-2000 per 100,000 individuals worldwide. The age distribution of Non ossifying fibroma is between 5-15 years.

Imaging techniques cannot always distinguish between malignant tumours and other aggressive lesions of bone, such as osteomyelitis. Therefore, the terms 'benign' and 'malignant' are best avoided when describing possible bone tumours. Rather, the terms 'aggressive lesion' and 'non-aggressive lesion' are frequently used to describe imaging features of suspected bone tumours ORIF (OPEN REDUCTION INTERNAL FIXATION) Surgery of bringing broken bones together and using hardware to help healing of broken bones nonossifying fibroma: a loculated osteolytic focus of cellular fibrous tissue, which slightly expands a bone, usually near the end of a long bone in older children; similar to fibrous cortical defect , although larger An aneurysmal bone cyst is rarely found secondary to nonossifying fibroma, and the diaphyseal location is atypical for nonossifying fibroma, both of which made diagnosis challenging. Conclusion The current case is a reminder to clinicians that, although rare, nonossifying fibroma can be associated with aneurysmal bone cyst, and both can occur in the diaphysis of long bones Enlarging nonossifying fibroma mimicking aggressive bone tumour V Wadhwa, RS Thakkar, JA Carrino, A Chhabra The Russell H.
