Résumé
Objective To study the CT findings of abdominal tuberculosis in patients with AIDS.Methods CT imaging features of abdominal tuberculosis in 33 patients with AIDS were retrospectively analyzed. Results Abdominal lymph adenopathy were observed in 23 cases (69. 7%, 23/33 ).Hepatosplenomegaly were observed in 10 cases (30. 3%, 10/33). Multiple low density nodes in spleen were observed in 14 cases(42. 4%, 14/33)including 9 cases of diffuse, low density nodes (27. 3% ,9/33). Low density lesions in liver were observed in 7 cases (21.2%, 7/33 ) including a case of tuberculous abscess (3.0%, 1/33 ) . Peritoneum and epiploon involvements were found in 5 cases ( 15.2%, 5/33 ) with associated ascites in 2 cases ( 6. 1%, 2/33 ) . Thickening of intestines wall were observed in 4 cases ( 12. 1% ,4/33). Destruction of lumbar vertebra with cold abscess was observed in 1 case (3.0% ,1/33).Abscess in psoas was observed in 1 case (3.0%, 1/33). Conclusion Abdominal tuberculosis in patients with AIDS usually involves multiple organs in the abdomen. CT has an important role in the detection and following up examination of these lesions.
