There was mature periosteal reaction
and a high intensity split cortex along the ulnar margin.
The lateral view of the right tibia showed proliferative and lytic periosteal reaction
, predominantly proliferative in the distal third of the tibia and right talus, exceeding the articular line.
As long as there is no additional pyogenic infection, periosteal reaction
is rarely seen (9).
There was no cortical erosion, periosteal reaction
, or pathological fracture [Figure 1].
It is characterized by its histologic appearance of being predominantly chondroblastic with areas of osteoid and its radiographic appearance of a periosteally based lesion with periosteal reaction
projecting perpendicularly into the associated soft tissue and has been found to have a lower propensity for metastasis compared to conventional, high-grade medullary osteosarcoma [1-7].
Histological osteomyelitic changes (periosteal reaction
, cortical bone, and medullary canal) were compared between the groups with a Wilcoxon rank sum test.
Radiographs obtained demonstrated a lytic, expansile, geographic lesion with no cortical disruption or periosteal reaction
There was no evidence of periosteal reaction
, osteolysis, or cloacal openings seen anywhere along the left proximal femur.
Orthopantomogram showed sclerotic change at the right body of the mandible with periosteal reaction
The bone may react to the lesion with a periosteal reaction
Lateral, ventrodorsal, and intraoral radiographs of masses of the skull and mandible are necessary to determine precise location within the bone, extent of bony involvement, margination of the lesion, and the presence or absence of a periosteal reaction
or bone lysis (McCAULEY et al., 2000).
Focal periosteal reaction
accompanied by endosteal thickening of the lateral femoral cortex is described as focal lateral thickening.
