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.
The brown tumor is a bone lesion that arises in settings of excess osteoclast activity, such as hyperparathyroidism. They are a form of osteitis fibrosa cystica. It is not a neoplasm, but rather simply a mass. It most commonly affects the maxilla and mandible, though any bone may be affected. [1] Brown tumours are radiolucent on x-ray.
X-ray of a giant-cell bone tumor in the head of the fourth metacarpal of the left hand. On X-ray, giant-cell tumors (GCTs) are lytic/lucent lesions that have an epiphyseal location and grow to the articular surface of the involved bone. [8] Radiologically the tumors may show characteristic 'soap bubble' appearance. [9]
They are lytic lesions that usually contain calcified chondroid matrix (a "rings and arcs" pattern of calcification), except in the phalanges. They may be central, eccentric, expansile or nonexpansile. Differentiating an enchondroma from a bone infarct on plain film may be difficult.
The vast majority of clinically significant bone lesions are detectable by age 10 years, with few new and almost no clinically significant bone lesions appearing after age 15 years. [8] Total body scintigraphy is useful to identify and determine the extent of bone lesions, and should be performed in all patients with suspected fibrous dysplasia.
Medical imaging typically shows a well defined radiolucent lesion, with a distinct multilocular appearance, sometimes looking like bubbles. [2] It is usually around 1–2 cm in size, but be as large as 7 cm. [ 3 ] They consist of foci consist of collagen rich connective tissue , fibroblasts , histiocytes and osteoclasts . [ 2 ]
