Osteosclerosis is a disorder characterized by abnormal hardening of bone and an elevation in bone density. It may predominantly affect the medullary portion and/or cortex of bone. Plain radiographs are a valuable tool for detecting and classifying osteosclerotic disorders. [1] [2] It can manifest in localized or generalized osteosclerosis.
infection in the bone leads to an increase in intramedullary pressure due to inflammatory exudates; the periosteum becomes stripped from the ostium, leading to vascular thrombosis; bone necrosis follows due to lack of blood supply; sequestra are formed; The sequestra are surrounded by sclerotic bone which is relatively avascular (without a ...
Condensing osteitis, also known as focal sclerosing osteomyelitis, is a rare periapical inflammatory condition characterized by the formation of sclerotic bone near the roots of premolars and molars. This condition arises as a response to dental infections, such as periapical pulp inflammation or low-intensity trauma.
Sclerosis (from Ancient Greek σκληρός (sklērós) 'hard') is the stiffening of a tissue or anatomical feature, usually caused by a replacement of the normal organ-specific tissue with connective tissue. The structure may be said to have undergone sclerotic changes or display sclerotic lesions, which refers to the process of sclerosis.
Osteolytic lesion at the bottom of the radius, diagnosed by a darker section that indicates a loss of bone density. An osteolytic lesion (from the Greek words for "bone" (ὀστέον), and "to unbind" (λύειν)) is a softened section of a patient's bone formed as a symptom of specific diseases, including breast cancer and multiple myeloma.
Radiographs in osteoid osteoma typically show a round lucency, containing a dense sclerotic central nidus (the characteristic lesion in this kind of tumor) surrounded by sclerotic bone. The nidus is seldom larger than 1.5 cm. [citation needed] The lesion can in most cases be detected on CT scan, bone scans and angiograms.
The affected foot tends to have a sclerotic and flattened navicular bone. Symptoms may last for a few weeks or may continue to be present for up to 2 years. [ 4 ] An indication of the symptoms residing is the resolution of the acute inflammation and obvious healing of the foot.
More than 80% of patients also reported abnormalities of the skull. Common symptoms include craniofacial hyperostosis, which is the excessive growth of bone in the skull and face. Skull base sclerosis, periorbital sclerosis, hypoplastic mandibular condyle, and absent paranasal or frontal sinuses are present in rare cases. [6] [7]
