Abstract

A 75-year-old man, who had been diagnosed with small lymphocytic lymphoma with cervical localization, underwent 18F-FDG PET/CT with iodinated contrast medium due to the appearance of cervical swelling suspected of illness relapse. PET/CT revealed intense 18F-FDG uptake in multiple cervical and subdiaphragmatic lymph nodes and in the left parotid. Moreover, diffuse uptake and wall thickening of the colon were evident; endoscopy with biopsy revealed a diffuse large B-cell lymphoma. Transformation into a more aggressive lymphoma occurs in 2% to 8% of small lymphocytic lymphoma, the so-called Richter syndrome. Extranodal localization in the sigmoid colon is an extremely rare site for transformed lymphoma.
