Abstract: Objective To analyze and investigate the CT imaging features and pathological results of AIDS related lymphoma, improving the cognition of acquired immunodeficiency syndrome (AIDS) related lymphoma. Methods Data of 39 cases with biopsy-pathologically proved AIDS-related lymphoma (ARL) were retrospectively analyzed, the specific imaging features of ARL were summarized. Results All the pathological types of 39 cases with ARL were non-Hodgkin's lymphomas (NHL); There were 39 lymphomas of lymph node, the main manifestations were enlargement of lymph nodes, including axillary lymph nodes (n=16), cervical lymph nodes (n=9), mediastinal and lung lymph nodes (n=7), abdominal lymph nodes(n=6), inguinal lymph node (n=1); there were 34 extranodal lymphomas, the main manifestations were space-occupying lesions, including soft tissue mass (n=20), liver (n=12), bone/cartilage (n=10), digestive tract (n=8), lung (n=6), adrenal gland (n=4), kidney (n=3), spleen (n=3), pancreas (n=2), muscle (n=2), parotid (n=1), cholecyst (n=1), prostate (n=1), seminal vesicle (n=1) and bladder (n=1), respectively. Conclusion NHL is the primary type of ARL. The main imaging features were extensive lymphnodes involvement and extranodal lesions. Though the imaging manifestations of AIDS complicated with lymphoma were well correlated with pathology findings, the imaging findings still need to be combined with pathological findings to obtain definite diagnosis.
