Caption: Figure 3: A 35-year-old male with frontal radiograph of the distal right forearm: there is
permeative mixed sclerosis and lucency in the distal radial and ulnar metaphysis and epiphysis (arrows).
However, radiographs at follow-up demonstrated a
permeative lesion with ill-defined margins and soft tissue extension, strongly suggestive of a malignancy.
5.) Particularly when osteosarcomas occur in diaphyseal rather than metaphyseal regions, they may exhibit layered, onionskin periosteal reactions.[1] It is important to note that rapidly expanding osteosarcoma tumors, which are typified by
permeative bone destruction, may provoke no visible periosteal reactions.
The mandible was described as irregular and "moth-eaten" in appearance, with diffuse enlargement, suggesting a
permeative process.
The property of being a citizen of the PRC is neither emergent like shape nor '
permeative' like uniform density and yet it is wholly located wherever a citizen of the PRC happens to be.
Similar to other aggressive osseous tumors, bony manifestations include
permeative, moth eaten lucencies, a wide zone of transition and associated soft-tissue mass.
Histologically, chondrosarcomas are composed of malignant cells with abundant cartilaginous matrix, hypercellularity, plump nuclei, binucleate cells,
permeative pattern and entrapment of bony trabeculae.
In contrast, malignant lesions often have a "moth-eaten" or
permeative appearance.
Radiographically, most low-grade osteosarcomas involve the metadiaphysis with cortical bone destruction and a
permeative growth pattern.
Radiological survey revealed multiple new and old
permeative lesions causing marrow expansion, cortical thinning and microfractures in metadiaphyseal regions of long bones (Figure-1 and 2).
