General consideration
? Can affect any organ in the abdomen ? Importance of clinical context in diagnosis
?High-risk population ：immunocompromised patients, especially AIDS （免疫抑制的病人） ?Typical symptoms: such as diarrhea, fever etc （腹泻、发热等） ?Laboratory findings （实验室检查）： serum and culture （血清和培养） ?Histologic analysis （组织学检查） ? Radiological findings might mimic many different disease ?Inflammatory disease ：Crohn's disease ?Neoplastic disease: Lymphomatosis, Peritoneal carcinomatosis
