A skeletal survey (also called a bone survey [1]) is a series of X-rays of all the bones in the body, or at least the axial skeleton and the large cortical bones. A very common use is the diagnosis of multiple myeloma, where tumour deposits appear as "punched-out" lesions.
Bone metastasis, or osseous metastatic disease, is a category of cancer metastases that result from primary tumor invasions into bones. Bone-originating primary tumors such as osteosarcoma , chondrosarcoma , and Ewing sarcoma are rare; the most common bone tumor is a metastasis. [ 1 ]
A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis). [1]
Pulmonary metastases shown on Chest X-Ray. The cells in a metastatic tumor resemble those in the primary tumor. Once the cancerous tissue is examined under a microscope to determine the cell type, a doctor can usually tell whether that type of cell is normally found in the part of the body from which the tissue sample was taken.

The diagnostic examination of a person with suspected multiple myeloma typically includes a skeletal survey. This is a series of X-rays of the skull, axial skeleton, and proximal long bones. Myeloma activity sometimes appears as "lytic lesions" (with local disappearance of normal bone due to resorption) or as "punched-out lesions" on the skull ...
In the detection of bone metastases, skeletal scintigraphy (bone scan) is very sensitive and is recommended as the first imaging study in asymptomatic individuals with suspected breast-cancer metastases. [17] X-ray radiography is recommended if there is abnormal radionuclide uptake from the bone scan and in assessing the risk of pathological ...
A bone tumor might present with a pathologic fracture. [1] Other symptoms may include fatigue, fever, weight loss, anemia and nausea. [2] [3] Sometimes there are no symptoms and the tumour is found when investigating another problem. [2] [3] Diagnosis is generally by X-ray and other radiological tests such as CT scan, MRI, PET scan and bone ...
The tumor is solid, hard, irregular ("fir-tree," "moth-eaten", or "sun-burst" appearance on X-ray examination) due to the tumor spicules of calcified bone radiating at right angles. These right angles form what is known as a Codman triangle, which is characteristic but not diagnostic of osteosarcoma. Surrounding tissues are infiltrated.
