Radiographs of the right ankle joint demonstrate a well-defined cortical based sclerotic lesion involving the distal diaphysis of the right tibia. No soft tissue component, cortical breakthrough or periosteal reaction. This is a nonaggressive lesion and …

2025年1月10日 · Non-ossifying fibromas (NOF) are benign and generally self-limiting osteoclastic giant cell-rich bone tumors typically found in the metaphyses of long bones. They are classified as osteoclastic giant cell-rich bone tumors 1,2. NOFs account for the 'N' in the popular mnemonic for lucent bone lesions FEGNOMASHIC.

Nonossifying fibromas (NOFs) are the most common benign (not cancerous) bone tumor in children. It is estimated that 30 to 40% of people under the age of 20 have an NOF, although few will have any symptoms. NOFs are often discovered by chance when a patient requires X-rays for another reason, such as a knee injury. These tumors:

Characteristics of a benign lesion, most probably a healing non-ossifying fibroma (NOF). At lower edge of scan, tiny structure in the tibiotalar joint, devoid of signal on all sequences - probably a loose body. As exemplified here, healing non-ossifying fibroma can …

3 天之前 · Non-Ossifying Fibromas are benign fibrogenic lesions that result from dysfunctional ossification that are most commonly found in the metaphysis of long bones. Patients typically present between the ages of 5 and 15 with an asymptomatic …

Non-ossifying fibromas (NOFs) are common lesions most frequently found in the growing bones of children and adolescents. Although NOFs are benign, their presence as incidental findings often triggers further investigation as they are sometimes mistaken for more sinister bone lesions such as aneurysmal bone cysts.

2021年10月10日 · Non-ossifying fibromas are the most common benign bone tumor in children, affecting up to 40%. They are made of fibrous tissue and grow on long bones, especially the legs. They usually appear as a solitary growth. They don’t spread or turn to cancer. Non-ossifying fibromas go away on their own when the child has fully grown.

Non-ossifying fibroma (NOF) is one of the most commonly seen benign bone tumours. Although renowned for their benign behaviour and tendency for spontaneous healing, these tumours can occasionally exhibit an aggressive course. Few published papers have focused on the treatment options of symptomatic NOFs.

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 ...

Most lesions heal spontaneously by being replaced with normal bone . Migrate away from epiphysis; May undergo pathologic fracture or rarely cause rickets. Do not undergo malignant transformation
