Diffuse Large B-Cell Lymphoma Infiltrating Limb Bones With a Few Lymphadenopathy Revealed on Whole-Body 18F-FDG PET/CT.
A 74-year-old man presented to our hospital for a 2-month history of worsening feet and left hand swelling pain. Computed tomography reconstruction image and sagittal images of the left foot demonstrated multiple and irregular bone destruction. Orthopedic surgeon suspected tuberculosis or primary skeletal malignancy. ¹⁸F-FDG PET/CT revealed bone destruction and abnormal activity mainly in bones of both upper and lower extremities and a few lymphadenopathy at the region of left axilla and groin. Diagnosis of diffuse large B-cell lymphoma was eventually made. Subsequently, the patient was transferred to the department of oncology and responded well to antilymphoma therapy.
