Enlarged lymph nodes are common imaging findings on routine multi-detector computed tomography, ultrasound, and magnetic resonance examinations of the abdomen and pelvis. The purpose of this exhibit is: 1) To list the non-neoplastic causes of lymphadenopathy in the abdomen and pelvis. 2) To review the epidemiological, clinical and pathological features of non-neoplastic entities presenting with abdominopelvic lymphadenopathy. 3) To present the characteristic imaging features (MDCT, MRI, US) with emphasis on pattern approach to differential diagnosis.  

1) Review of major nodal stations in the abdomen and pelvis. 2) Present clinical, pathological and imaging features of a wide array of non-neoplastic conditions resulting in abdominopelvic lymphadenopathy including, but not limited to: Nonspecific lymphoid hyperplasia,Viral infections (HIV, HBV, HCV Infectious mononucleosis), Whipple disease, Celiac disease, Autoimmune diseases (ex. SLE), Castlemans disease, Kikuchi lymphadenitis, Granulomatous lymphadenitis (ex. Sarcoidosis, Chron’s, TB, Syphilis), Rosai-dorman disease (sinus histiocytosis), Storage disorders, and drugs. 3) Discuss a pattern approach based on clinical and imaging features.
