AB  - Immunoreconstitution inflammatory syndrome (IRIS) was reported to occur in 7-13% 
      of AIDS patients on anti-retroviral therapy (ART). IRIS due to Mycobacterium 
      infection is one of the most difficult IRIS types to manage. A male patient in 
      his early 70s was diagnosed with AIDS and treated with an ART. One year after 
      starting ART, abdominal ultrasound was performed for screening and a 4 cm 
      hypoechoic mass was found from the outside of the stomach to the surface of the 
      hepatic lateral segment. Based on various imaging tests, including contrast CT, a 
      malignant tumor, such as malignant lymphoma, was suspected. Then, a percutaneous 
      tumor biopsy was performed. Pathologically, the tumor was recognized as 
      mycobacterial granulomas. Disseminated mycobacterium avium complex can produce 
      granulomas anywhere in the body. The patient was diagnosed with a mycobacterial 
      infection associated with IRIS. When an intra-abdominal mass is found in a 
      patient with HIV, both malignancy and mass formation due to opportunistic 
      infections should be considered differential diseases.
