Before and After Treatment Characterization of Cerebrospinal Disease in Bing-Neel Syndrome Using 18F FDG PET/MRI.

Bing-Neel syndrome is a rare neurological complication of Waldenstrom macroglobulinemia. We present the case of a 71-year-old man who underwent prechemotherapy and postchemotherapy FDG PET/MRI scan for the evaluation of cerebrospinal disease. In light of limited literature and lack of consensus guidelines on the role of metabolic imaging, we aim to highlight the utility of FDG PET/MRI in the diagnosis and response assessment in Bing-Neel syndrome.
