Abstract Purpose To evaluate the use of sonography in the assessment of compressibility of the affected bowel in the differential diagnosis of gastrointestinal (GI) lymphoma. Methods Thirty‐two cases of advanced gastric cancer, 28 cases of advanced colon cancer, 7 cases of gastric lymphoma, and 6 cases of colon lymphoma were included in the study. To assess the compressibility of the affected bowel, a transducer was used to exert external compression. Deformation of the tumor and its lumen by compression was considered to indicate positive compressibility. Results Compressibility was absent in advanced gastric and colon cancer but was present in 11/13 (85%) cases of GI lymphoma. In the diagnosis of GI lymphoma, compressibility showed 85% (11/13) sensitivity, 97% (58/60) specificity, and 95% (69/73) overall accuracy. Conclusion Compressibility of the affected bowel is a useful clue in the diagnosis of GI lymphoma. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2008
