Abstract:
Objective:To summarize endorectal ultrasound（ERUS）findings of rectal lymphoma（RL）and evaluate its clinical value for preoperative diagnosis.Methods:Nine RL patients between Jan 2015 and March 2025 in the Sixth Affiliated Hospital of Sun Yat-Sen University were included in this retrospective study. ERUS findings including lesion location，size，echogenicity，mucosal integrity，depth of infiltration，and blood flow characteristics were reviewed. The diagnostic performance of ERUS was evaluated using pathology as the gold standard.Results:ERUS features of RL included extensive bowel wall involvement（≥1/2 circumference in 8/9 cases），intact mucosa（7/9），homogeneous markedly hypoechoic echogenicity（6/9），and Adler grade 3 blood flow（9/9）. No case presented bowel obstruction；three cases involved multi- segmental bowel. All four cases who received ultrasound-guided biopsy reached conclusive diagnosis，while 2 of them were infeasible for endoscopic biopsy.Conclusions:Typical ERUS findings of RL include extensive infiltration，preserved mucosa，and homogeneous markedly hypoechoic echogenicity. ERUS could clearly show the submucosal infiltration pattern and bowel wall layers，and significantly improve preoperative diagnostic accuracy in combination with ultrasound-guided biopsy.
