False-positive [18F]fluorodeoxyglucose-avid lymph nodes on positron emission tomography - Computed tomography after allogeneic but not autologous stem-cell transplantation in patients with lymphoma
Hematopoietic Stem Cell Transplantation
Tomography, X-Ray Computed
Twenty percent (21 of 107) of patients with an allogeneic stem-cell transplantation demonstrated FDG-avid lymph nodes up to 1.5 cm in short axis on PET/CT, which did not represent active lymphoma. After allogeneic stem-cell transplantation of patients with lymphoma, benign FDG-avid ≤ 1.5 cm lymph nodes can mimic malignancy.
