A 63-year-old man presenting with peripheral neuropathies was diagnosed of Waldenström’s macroglobulinemia, and Bing–Neel syndrome was subsequently confirmed via cerebrospinal fluid examinations. Besides involvement in bone marrow, lymph nodes, as well as the thoracic and sacral nerve root, 68Ga-Pentixafor PET/CT detected active tracer uptake in bilateral choroid plexus, which was negative in 18F-FDG PET/CT, possibly suggesting the involvement of Bing–Neel syndrome. The coexisting pituitary macroadenoma was FDG-avid but negative in 68Ga-Pentixafor PET/CT. After six cycles of chemotherapy, the follow-up PET/CT showed complete remission of the previous disease, including the high uptake of 68Ga-Pentixafor in choroid plexus. However, the hypermetabolic pituitary macroadenoma remained unchanged.
