Tuberculous Abscesses in Patients with AIDS

Five cases of large tuberculous abscesses in patients with AIDS were observed over a 2-year period at the New York Veterans Affairs Medical Center. These cases represent 11.6% of the 43 cases of tuberculosis diagnosed in patients with AIDS during that period. The abscesses were located in the liver, abdominal wall, psoas muscle, mediastinum, and peripancreatic area. All patients presented with localized pain or swelling, and four of five patients had fever. The diagnosis was made on the basis of detection of abscesses on computed tomography (CT) and the results of culture of abscess material obtained by CT-guided aspiration. CT-guided therapeutic drainage was performed in two cases. Despite administration of therapy, two of five patients died of tuberculous infection. Formation of tuberculous abscesses appears to be a common complication of tuberculosis in patients with AIDS. This diagnosis should be considered for patients with AIDS who have fever and localized pain or swelling.
