What is a lucent lesion mean?
Listen to pronunciation. (LIH-tik LEE-zhun) Destruction of an area of bone due to a disease process, such as cancer.
What is a bone lucency?
Bone lesions are areas of bone that are changed or damaged. Causes of bone lesions include infections, fractures, or tumors. When cells within the bone start to divide uncontrollably, they are sometimes called bone tumors. Most bone lesions are benign, meaning they are not cancerous.
Do bone lesions need surgery?
Usually, however, surgery is needed. Surgery removes the tumor and rebuilds new, healthy bone where the tumor was removed. At the Cedars-Sinai Orthopedic Center, specialized, minimally invasive techniques are used to protect the surrounding healthy tissue.
What is an expansile lesion?
An expansile vertebral lesion may be osteolytic, osteoblastic, or mixed (Table I). The margin of a benign lytic lesion iswell defined and sclerotic, whereas an aggressive, malignant lesion shows ill-defined borders. Recognition of the tumor matrix isalso important.
Are lucent lesions cancerous?
Lucent lesions of the sternum should be considered malignant until proven otherwise (Helms CA, personal communication, 1983). Keep in mind that the classic descriptions of bone tumors that you spend so much time studying are for untreated lesions.
What does lucency mean in medical terms?
A pale area
Lucency meaning (medicine) A pale area revealed in radiography, computed tomography, or similar examination technique.
Does lucency mean fracture?
The process of fracture healing On radiographs, there may be increased lucency of the fracture during this stage due to bone resorption. Progenitor cells within the granulation tissue proliferate and begin to differentiate into fibroblasts and chondroblasts.
What does Expansile mean in medical terms?
ex·pan·sile (eks-pants’ĭl), Related to expansion or inclined to enlarge or expand.
What is lucency on a CT scan?
CT scans were evaluated by a neuroradiologist for the presence or absence of white matter lucencies (WML). WML were defined as patchy or diffuse areas of decreased attenuation involving only white matter and with no change in adjacent ventricles or sulci.
What does lucency mean on a CT scan?
What is a metaphyseal lesion on the tibia?
occurring in the tibia. The lesion is by far most common in the mature skeleton following physeal closure, at which time it is a predominantly epi- physeal lesion with secondary extension into the metaphysis (Fig 7). In those rare cases of gi- ant cell tumor that occur prior to physeal closure, the lesions tend to be metaphyseal in location.
Where are lucent lesions located on the bone?
Most expansile, lucent lesions are located in the medullary space of the bone. However, we can further define the location of the lesion by noting its relationship to the physis. Many lesions tend to occur in a “favorite” part of the bone.
What is the differential diagnosis for metaphyseal lesions?
The differential diagnosis for metaphyseal lesions includes: 1. Greenspan A, Remagen W. Differential diagnosis of tumors and tumor-like lesions of bones and joints.
What are the lesions of the tibia that cause cortical destruction?
Categorization of lesions of the tibia into those that cause cortical destruction and those that cause cor- tical proliferation can help narrow the broad differential diagnosis. Le- sions that cause cortical destruction include nonossifying fibroma, fi- brous dysplasia, osteofibrous dysplasia, aneurysmal bone cyst, giant
