18F-FDG and 68Ga-Pentixafor PET/CT Findings in Patient With Multicenter Castleman Disease

ABSTRACT: Castleman disease is a rare lymphoproliferative disorder primarily affecting lymph nodes, including unicentric and multicentric types. The multicentric form is rarer and can often be misdiagnosed as lymphoma. Here, we report 18 F-FDG and 68 Ga-pentixafor PET/CT findings in a case of Castleman disease involving the nasopharynx and multiple lymph nodes.
