OBJECTIVE To study the distribution of abdominal and pelvic lymphadenopathy innon-Hodgkin lymphoma (NHL)in Chinese patients. METHODS CT images of 241 NHL patients with abdominal and/or pelvic lymphadenopathy were reviewed. Among them, clinical and image data from 96 patients fulfilled the requirements for the analysis: 1. Abdominal and/ or pelvic lymphadenopathy detected by CT in untreated patients (n=74). 2. Recurrent patients: new lesions in abdominal or pelvic lymph nodes who never had any nodular lesion by previous abdominal and/or pelvic CT (n = 14). 3. Treated patients who did not have abdominal and/or pelvic CT previously, showed regression of initial disease for at least 6 months after chemotherapy and subsequently showed abdominal and/or pelvic lymphadenopathy (n =8). According to the Clinical Schema for Lymphoid Tissue, these patients were divided into 3 histologic subtypes: indolent (IL; n=31), aggressive (AL; n=61) and very aggressive (VAL; n=2) lymphoma. The remaining 2 cases were unclassified lymphoma (UCL). Both abdomina
