The first one is a white woman aged 65 and the second one is a black woman aged 70, both diagnosed with FOD, revealed by secondary infections. This fact may support the hypothesis that OD lesions represent a dysplastic process related to hormonal imbalance, which influences bone remodeling Kramer et al.
You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. In more mature lesions, there may be woven and lamellar bone and cementum-like tissue coalesces into fused sclerotic masses of globular basophilic calcifications. Fibrous dysplasia is the most common cause of a benign expansile lesion of a rib see rib lesions.
Fibrous dysplasia is not hereditaryand there has never been a case of transmission from dis;lasia to child.
Regarding the treatment of FOD, in case of asymptomatic lesions, treatment and biopsy are not indicated. Treatment in fibrous dysplasia is mainly palliative, and is focused on managing fractures and preventing deformity.

It depends on the stage or the degree of calcification of the lesion. If a mass effect is severe, then surgical decompression may be considered. A more surgical approach is required when conservative treatment fails to control a recurrent lesion. It should be noted that many reported cases may relate to previous treatment with radiation therapy 6.
MRI is not particularly useful in differentiating fibrous dysplasia from other entities as there is marked variability in the appearance of the bone lesions, and they can often resemble a tumor or more aggressive lesions. Symptoms such as dull pain or drainage, and mucosal ulceration, are almost always associated with exposure of sclerotic calcified masses in the oral cavity Bencharit et al.
