The Value of 18F-FDG PET/CT in Diagnostic Procedure of Intravascular Large B-Cell Lymphoma Presenting Fever of Unknown Origin and Pulmonary Hypertension as an Initial Manifestation

Clin Nucl Med. 2016 Jun;41(6):506-7. doi: 10.1097/RLU.0000000000001188.

Abstract

A 57-year-old man presented with fever of unknown origin and pulmonary hypertension. An F-FDG PET/CT scan was performed to evaluate the source of fever, which showed diffuse, homogeneously increased FDG uptake in both lungs, which prompted the transbronchial lung biopsy. The pathological examination from biopsy specimen demonstrated intravascular large B-cell lymphoma.
