• DW improves MR diagnostic accuracy to detect infection of PFC • Infected PFCs show lower ADC compared to non-infected ones (P < .031) • DW-MR images are easy to interpret especially for non-experienced radiologist.
We describe a case of light chain deposition disease presenting as worsening of renal failure with a lytic femoral bone lesion discovered by sonography. Although sonography cannot be considered to be the test of choice in evaluating multiple myeloma, this technique may allow the detection and the biopsy of osteolytic bone lesions, particularly in accessible locations. Differential diagnosis is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
