Overview
X-ray may be helpful in the diagnosis of multiple myeloma. Findings on X-ray suggestive of multiple myeloma include punched out bony lesions, generalized osteopenia, and hair-on-end appearance.[1][2] In some cases, MRI may be needed if X-ray is insufficient for diagnosis.
X-ray
- Simple radiography is the current gold standard for the initial diagnosis and evaluation of lytic lesions of multiple myeloma.[1]
- The long bones and the spine must always be evaluated while the evaluation of other bones merit consideration based on the patient's symptoms.[1]
- A series of plain films, or skeletal survey, is essential in not only the diagnosis of multiple myeloma, but also in assessing response, and pre-empting potential complications (e.g. pathological fractures). A typical skeletal survey consists of the following films:[1]
- The vast majority of lesions seen on plain radiography are purely lytic. Lytic lesions are sharply defined and "punched-out" in appearance, with endosteal scalloping when abutting cortex. The lesions are sclerotic in only 3% of patients.[1]
- The X-ray is the most inexpensive diagnostic modality for lytic lesions. In some cases, MRI may be warranted, as MRI has a higher sensitivity than X-ray.
- X-rays should be avoided in pregnant patients with multiple myeloma. MRI can be done instead.
