Abstract
A 38-year-old man with a history of renal transplantation presented
with a 3-month history of bilateral neck swelling. Ultrasonography of
the neck showed multiple enlarged lymph nodes at the bilateral neck.
Histologic examination of a specimen from an excisional biopsy at right level
II cervical lymph node revealed polymorphic posttransplant lymphoproliferative
disorder. F-18 fluorodeoxyglucose (FDG) positron emission tomography/
computed tomography scan was performed for further evaluation. The
scan revealed marked enlargement and intense hypermetabolism of the
lymph nodes along the bilateral cervical lymph node chains (Fig. 1). Several
reports have described that diverse infectious or inflammatory disorders and
malignant diseases show various degree of FDG uptake of cervical lymph
nodes. This case illustrates that the possibility of posttransplant lymphoproliferative
disorder should be considered in renal transplant patients with
increased FDG uptake of cervical lymph nodes on F-18 FDG positron
emission tomography/computed tomography scan.
Key Words: posttransplant lymphoproliferative disorder (PTLD), cervical
