Lucent or osteolytic bone lesions are descriptive radiological terms. Pathologically these findings can be represented by a wide spectrum of conditions including neoplastic, inflammatory and metabolic causes. These lesions are characterized either by the replacement of bone matrix by other types of tissue including soft tissue, fluid or fat. They a...
As per definition, osteolytic lesions are radiolucent on plain radiographs and hypodense on CT with lower attenuation than the adjacent trabecular bone 1. This includes lesions with nonsclerotic fatty, liquid or solid soft tissue components. A better and more consistent quantitative definition for the term lucent does not yet exist 1. Osteolytic le...
The differential diagnosis of lucent or osteolytic bone lesions is vast and can be narrowed down according to the following factors 1, 8,9: 1. aggressive features 2. history of malignancy 3. intralesional fatty components 4. location within the bone and the skeleton: 4.1. cortical, juxtacortical, centric or eccentric within cancellous bone 4.2. epi...
aggressive features: might require an oncological referral and/or biopsy 1history of malignancy: will almost always require additional imaging, follow-up or oncologic referralintralesional fatty components in the absence of aggressive features and a history of malignancy: almost always indicate a benign entity- Ammar Ashraf
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. The favored locations are listed in the figure below.

Jan 17, 2016 · Definition. Bone tumors can be divided into primary and secondary osseous tumors. The knee joint is the most common localization of primary tumors of the bone, occurring as malignant, potentially malignant, benign, or tumorlike lesions.
Although there are innumerable processes that can lead to focal lesions in bone, we present here a review of commonly encountered bone lesions [Table 1] that can mimic bone tumors and discuss the key imaging and clinical features that can help distinguish these entities from neoplasms.
