Because an individual with an<unk>  has few symptoms, diagnosis is sometimes made during a routine physical examination, or if the presence of the tumor leads to a fracture. In addition to a complete medical history and physical examination, diagnostic procedures for<unk>  may include the following: * x-ray - On plain film, an<unk>  may be found in any bone formed from cartilage. They are lytic lesions that usually contain calcified chondroid matrix (a "rings and arcs" pattern of calcification), except in the phalanges. They may be central, eccentric, expansile or nonexpansile. Differentiating an<unk>  from a bone infarct on plain film may be difficult. Generally, an<unk>  commonly causes endosteal scalloping while an infarct will not. An infarct usually has a well-defined, sclerotic serpentine border, while an<unk>  will not. When differentiating an<unk>  from a chondrosarcoma, the radiographic image may be equivocal; however, periostitis is not usually seen with an uncomplicated<unk> . * radionuclide bone scan - a nuclear imaging method to evaluate any degenerative and/or arthritic changes in the joints; to detect bone diseases and tumors; to determine the cause of bone pain or inflammation. This test is to rule out any infection or fractures. * magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. This test is done to rule out any associated abnormalities of the spinal cord and nerves. * computed tomography scan (Also called a CT or CAT scan.) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. A CT scan shows detailed images of any part of the body, including the bones, muscles, fat, and organs. CT scans are more detailed than general x-rays.
