FDG PET-MRI evaluation of synchronous gallbladder adenocarcinoma and POEMS syndrome

Radiol Case Rep. 2022 Sep 13;17(11):4294-4298. doi: 10.1016/j.radcr.2022.08.059. eCollection 2022 Nov.

Abstract

POEMS syndrome is a rare paraneoplastic syndrome associated with a plasma cell proliferative disorder. Gallbladder adenocarcinoma is a rare malignancy, with no association with POEMS syndrome. The plasma cell dyscrasia is routinely evaluated with advanced hybrid imaging to assess both anatomic and functional components. We present a case of a 59-year-old female with a known diagnosis of POEMS syndrome who underwent a whole-body restaging evaluation with hybrid positron emission tomography (PET) and magnetic resonance imaging (MR) to restage her plasma cell dyscrasia. She also had a prior diagnosis of gallbladder adenocarcinoma. Our case focuses on the value of PET/MR in this scenario as well as a rare case of osseous metastasis from gallbladder carcinoma.

Keywords: Gallbladder adenocarcinoma; PET-MRI; POEMS syndrome.
