title: Computed tomographic findings of abdominal tuberculosis--report of five cases.
abstract: Five patients with proven intra-abdominal tuberculosis were examined with computed tomography (CT) over a period of one year. This revealed hepatosplenomegaly in all five cases. Macroscopic nodules were noted in the liver and spleen in three cases. All three cases showed more severe involvement of the spleen over the liver. Other features were enlarged (para-aortic, para-caval, peripancreatic and mesenteric) nodes, ascites, stellate mesentery and thickened bowel wall. Incidental extra-abdominal findings included intrathoracic nodules, pleural effusion, pericardial effusion with constrictive pericarditis, bony osteomyelitis and psoas abscess. Follow-up CT was performed on four of the five cases and showed significant resolution of the above findings. In addition, one case showed calcification within a healing splenic nodule. The presence of macroscopic nodules detected on CT, especially in the spleen, is an unusual finding in prior reports. This paper attempts to account for its high local incidence and discusses the significance of other findings in the diagnosis of abdominal tuberculosis.
