MR appearance of multiple myeloma of the spine before and after treatment.

Bone metastases from head and neck paragangliomas: Uncommon MR findings in an uncommon condition—Report of three cases

“…Vertebral hemangiomas may contain both fatty and soft-tissue signal intensity, but they do not exhibit the concentric organi- zation of the different intensities found in the images from our patients. The description of a fatty halo has been described as the result of treatment in multiple myeloma (7). In the present study a fatty halo was spontaneously present and was not the result of a general or local treatment.…”

Transosseous cerebrospinal fluid fistula 14 years after Chiari decompression: presentation and management

“…3,5,8,10,13,15,18,19,21 Eosinophilic granuloma and malignant neoplasms are osteolytic rather than expansile lesions and thus differ in appearance from the current case. Although dermoid and epidermoid tumors and lymphatic malformations are often expansile rather than lytic, these lesions are not typically isointense to CSF on diffusion-weighted MR images, and thus are also distinct from the present case.…”

Comparison of whole-body MR imaging and conventional X-ray examination in patients with multiple myeloma and implications for therapy

“…So far, only few studies have demonstrated that MRI is an adequate method for follow-up of patients with multiple myeloma since changes in the signal intensity and the morphology of the lesions are seen during therapy and these changes correlate with the clinical parameters [35]. Up to now, however, no publication has evaluated the influence of MRI using a whole-body approach on the decision to initiate further specific therapy.…”
